Abstract
PURPOSE Spinal cavernous malformations (SCM) present a risk for intramedullary hemorrhage (IMH), which can cause severe neurologic deficits. Patient selection and time of surgery have not been clearly defined. METHODS This observational study included SCM patients who underwent surgery in our department between 2003 and 2021. Inclusion required baseline clinical factors, magnetic resonance imaging studies, and follow-up examination. Functional outcome was assessed using the Modified McCormick scale score. RESULTS Thirty-five patients met the inclusion criteria. The mean age was 44.7 ± 14.5 years, and 60% of the patients were male. In univariate analysis, the unfavorable outcome was significantly associated with multiple bleeding events (p = .031), ventral location of the SCM (p = .046), and incomplete resection (p = .028). The time between IMH and surgery correlated with postoperative outcomes (p = .004), and early surgery within 3 months from IMH was associated with favorable outcomes (p = .033). This association remained significant in multivariate logistic regression analysis (p = .041). CONCLUSIONS Removal of symptomatic SCM should be performed within 3 months after IMH when gross total resection is feasible. Patients with ventrally located lesions might be at increased risk for postoperative deficits.

Abstract
PURPOSE This study aimed to investigate the neurological outcome, trends and sequelae following surgical or conservative treatment of intramedullary spinal cord cavernous malformations (ISCCMs). METHODS A systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome measure was the change in the neurological status after surgery or conservative management. A logistic regression analysis investigating prognostic factors related to outcome was also performed. RESULTS Twenty-one studies with 1091 patients in total were included, of which 1005 (92.1%) underwent surgical resection and 86 (7.9%) were treated conservatively. Gross total resection was achieved in 95.7% of the patients and partial resection in 4.3%. Most lesions (60.2%) were located in the thoracic spine and presented with motor (60.4%) and sensory deficits (59.7%). In the long term, surgical treatment resulted in an improved neurological status in 36.9% of the patients, in 55.8% it remained stable, and in 7.3% it deteriorated compared to the preoperative state. In the conservative cohort, 21.7% improved, 69.6% remained stable, and 8.7% deteriorated. Solitary lesions, duration of preoperative symptoms less than 3 months as well as an improved post-operative neurological status were predictors of a favourable long-term outcome. CONCLUSIONS Whenever feasible, symptomatic patients with ISCCM are recommended to undergo surgery within 3 months from symptom onset. Absence of multiple lesions and, most importantly, post-operative symptom improvement foresee a favourable long-term outcome. Further research is warranted to discern the role of conservative treatment in symptomatic patients.

Abstract
OBJECTIVE Cavernous spinal cord malformations (SCMs) are believed to have a high rate of bleeding. The risk of intramedullary hemorrhage (IMH) or recurrent IMH and the neurological impact of bleeding events are important for clinical decision-making and could impact current treatment strategies. METHODS The authors screened their institutional database for patients with cavernous SCM treated between 2003 and 2020. Patients with complete MRI data sets and clinical baseline characteristics were included. Surgically treated patients were censored after cavernous SCM removal. Neurological functional status was obtained using the modified McCormick (MMcC) scale at diagnosis, first IMH, and second IMH. Kaplan-Meier and Cox regression analyses were performed to determine the cumulative 5-year risk for hemorrhage or rehemorrhage. RESULTS Seventy-one patients with cavernous SCM were analyzed. Cox regression analysis identified previous IMH (hazard ratio 7.86, 95% confidence interval 1.01-61.47, p = 0.049) as an independent predictor for rehemorrhage during the 5-year follow-up. The cumulative 5-year risk of bleeding or rebleeding was 41.3% for cavernous SCM. The MMcC score significantly deteriorated in 75% of patients after recurrent hemorrhage (p = 0.012). CONCLUSIONS During untreated 5-year follow-up, a considerably increased risk for hemorrhage or rehemorrhage was found in cavernous malformations of the spinal cord compared to cerebral cavernous malformations. Neurological function significantly deteriorates after the second bleeding. The probability of recurrent IMH increased significantly after initial presentation with hemorrhage.

Abstract
Cavernous malformations (CMs) of central nervous system are vascular malformations usually localized in the brain and rarely in the spinal cord. To date, these malformations are well studied. However, some problems of the management of this pathology are still unresolved. This is due to rare localization of intramedullary CMs in the spinal cord and difficult treatment of spinal pathology per se. To date, about 1000 cases of spinal CM are described in the literature. This review is devoted to natural course of disease and postoperative outcomes. These data allow getting a complete picture of modern concepts of the treatment of spinal CMs and formulating the questions requiring further discussion.

Abstract
OBJECTIVE We sought to examine the conservative treatment of symptomatic spinal cavernomas and evaluate the efficacy and safety of surgical management of spinal cord cavernous malformations. METHODS This meta-analysis included articles comparing outcomes of conservative treatment and surgical management of spinal cavernomas, published in the full-text form (from 2000 to June 31, 2020). Collected variables included first author name, country, covered study period, publication year, the total number of patients and at follow-up, bleeding, motor weakness, pain, bladder and/or bowel dysfunction neurologic improvement or deterioration after discharge, and the need for reintervention after subtotal surgical resection or hemorrhage. RESULTS After the initial searching and applying all exclusion and inclusion criteria, there were 9 articles left in the final article pool. The total number of patients was 396 with 264 (66.6%) undergoing surgical resection and 132 (33.4%) electing conservative management. Regarding motor weakness, bladder/bowel dysfunction, deterioration, and reintervention, the final results demonstrated no potential significant difference between the 2 groups. In regard to the subgroup of patients with bleeding, improvement, and pain, the results of the analysis showed a statistically significant difference between the 2 groups. CONCLUSIONS Patients who have experienced a hemorrhagic episode should consider surgical intervention, which decreases the risk of recurrent hemorrhage and further neurologic deterioration. In addition, surgical decompression obtained by resection of the hemorrhage and cavernoma seems to lead to slight neurologic improvement in some patients. In nonhemorrhagic cavernomas, conservative treatment might be optimal due to surgery-related morbidity risks.

Abstract
Cavernous malformations (CMs) are angiographically occult, low-flow vascular malformations of the central nervous system. They are acquired lesions, with approximately 80% of patients having the sporadic form and 20% the familial form of the disease. The lesions may also develop years after radiotherapy. At the microscopic level, they consist of endothelium-lined cavities (or "caverns") containing blood of different ages. The endothelium proliferates abnormally, and tight junctions are absent or dysfunctional, resulting in leakiness of the endothelium and clinical manifestations in some patients. Cavernous malformations can be an incidental finding or can present with focal neurologic deficits, seizures, or headache, with or without associated hemorrhage. Management of the CM lesion requires knowledge of the natural history of the disease compared with the risk of surgical intervention. Surgery is often considered for symptomatic patients with lesions in a noneloquent location. Medical management is warranted for symptoms related to the CM. Research aimed at understanding the genes and signaling pathways related to CMs have provided potential drug targets, and clinical trials are underway to determine whether medications reduce the risk of future bleeding without surgery or modify the disease course. In addition, recent epidemiologic data have aided practitioners in determining how to treat comorbid conditions in patients with a potentially hemorrhagic lesion. This review provides an overview of the epidemiology, presentation, and clinical management of CMs.

Abstract
BACKGROUND AND PURPOSE There is a relative paucity of radiology literature on spinal cord cavernous malformations (SCMs). We hypothesized that the classic MRI features of cavernous malformations are not highly prevalent. The purpose was to review MR imaging findings of SCMs with a focus on prevalence of hemorrhagic features, including adjacent intramedullary hemorrhage at initial presentation. METHODS In this single-institution study, 78 SCMs in 76 patients diagnosed on imaging/pathology were retrospectively evaluated for size, location, cord expansion, exophytic component, popcorn morphology, signal characteristics, including T1 weighted (T1w) and T2w rims, blood-fluid levels, and adjacent intramedullary hemorrhage. Intramedullary hemorrhage was defined as centrally and/or eccentrically located linear or flame shaped non-edematous signal abnormality extending longitudinally away from SCMs, distinct from lesional rim. RESULTS Sixty-three percent (49/78) of SCMs measured <1 cm in length, 78% (61/78) extended to the cord surface, 65% (51/78) were expansile, and 32% (25/78) were exophytic. Popcorn morphology was seen in 15% (12/78) on T1w and 22% (17/78) on T2w. Internal blood-fluid levels were evident in 4% (3/78). Sixty-nine percent (54/78) showed T2w hypointense rims; the T2w rim was complete/near-complete in 37% (29/78). A rim on T1w was visible in 49% (38/78); this was hyperintense in 58% (22/38). Adjacent intramedullary hemorrhage was seen in 45/78 (58%), was most commonly bidirectional in 67% (30/45) and eccentric in 68% (30/44). Cord edema was seen in 22% (17/78); 53% (9/17) also demonstrated intramedullary hemorrhage with edema. CONCLUSIONS The classically described popcorn morphology, internal blood-fluid levels, and complete/near-complete T2w hypointense rims are often absent on MRIs in SCMs. Adjacent intramedullary hemorrhage is frequently present, often eccentric and bidirectional.

Abstract
BACKGROUND AND AIM Cavernous malformations are low-flow vascular malformations of the central nervous system. Brainstem location and prior hemorrhage increase future hemorrhage risk. We sought to determine the influence of physical activity on hemorrhage risk. METHODS Consecutive patients with radiologically confirmed cavernous malformations participated in a prospective registry with structured, baseline interviews, surveys, and examinations. Patients were asked about unusual events prior to initial clinical presentation. Medical records and MRIs were reviewed. Patients were surveyed about their physical activity after receiving their diagnosis. Annual follow-up surveys to patients ascertained new hemorrhages. Follow-up terminated at last follow-up, hemorrhage, surgery, or death. Univariate analysis assessed the risk of physical activities on prospective hemorrhage. RESULTS Of 195 patients, 117 (60%) were female. Median diagnosis age was 41 years. After diagnosis, 103 (52.8%) patients returned the physical activity survey (cerebral n = 100; spine n = 3). Over 539.4 patient years, 23 had a prospective hemorrhage. Five patients were removed from analysis because they had less than 6 weeks of physical-activity exposure before censor. The remaining 98 had no difference in prospective hemorrhage risk than those patients participating greater than or equal to 3 times monthly in walking, running, greater than 20-pound or less than 20-pound weight lifting, or noncontact sports. Few (n = 5) reported contact-sport participation, scuba diving (n = 2), or high-altitude climbing (n = 1) greater than 3 times monthly. CONCLUSIONS Aerobic activity and noncontact sports do not increase hemorrhage risk in cerebral cavernous malformation; patients should not be restricted. Less is known about contact sports, high-altitude climbing, scuba diving, and those with spinal-cord cavernous malformation.

Abstract
Abstract
BACKGROUND
No prior reports have focused on the natural history and long-term outcomes of intramedullary spinal cord cavernous malformations (ISCCMs) in children.
OBJECTIVE
To investigate the clinical characteristics and long-term outcomes of pediatric ISCCMs and identify the risk of hemorrhage.
METHODS
We retrospectively reviewed a series of 20 pediatric patients (<18 yr old) from a consecutive series of 254 patients with ISCCMs evaluated at a single institution.
RESULTS
Of the 20 pediatric patients, 9 (45.0%) presented with a severe neurological and disability status. The annual hemorrhagic rate in pediatric patients was 8.2%/patient/year. After initial overt hemorrhage events, the annual overt rehemorrhage rate increased to 30.7%/patient/year. In 234 adult patients, the respective rates were 2.8% and 7.4%. Thoracic or lumbar level lesions (P = .002, OR = 3.425, 95% CI = 1.588-7.387) and rehemorrhagic events (P = .005, OR = 3.209, 95% CI = 1.415-7.279) were more likely to follow an aggressive course. There were no significant differences in the sex distribution, location and size of lesions, types of symptoms, likelihood of a severe neurological and disability status, or immediate and long-term postoperative outcomes between pediatric and adult patients with ISCCMs
CONCLUSION
The annual overt hemorrhage rate and rehemorrhage rate of ISCCMs were higher in affected children than in affected adults. Surgical resection of pediatric ISCCMs remains the preferred therapeutic option and provides favorable outcomes.

Abstract
OBJECTIVE Intramedullary cavernous hemangioma (CH) is a rare vascular lesion that is mainly characterized by the sudden onset of hemorrhage in young, asymptomatic patients, who then experience serious neurological deterioration. Despite the severity of this condition, the therapeutic approach and timing of intervention for CH remain matters of debate. The aim of this study was to evaluate the clinical characteristics of CH patients before and after surgery and to identify prognostic indicators that affect neurological function in these patients. METHODS This single-center retrospective study included 66 patients who were treated for intramedullary CH. Among them, 57 underwent surgery and 9 patients received conservative treatment. The authors collected demographic, symptomology, imaging, neurological, and surgical data. Univariate and multivariate logistic regression analyses were performed to identify the prognostic indicators for neurological function. RESULTS When comparing patients with stable and unstable gait prior to surgery, patients with unstable gait had a higher frequency of hemorrhagic episodes (52.4% vs 19.4%, p = 0.010), as assessed by the modified McCormick Scale. The lesion was significantly smaller in patients who underwent conservative treatment compared with surgery (2.5 ± 1.5 mm vs 5.9 ± 4.1 mm, respectively; p = 0.024). Overall, the patients experienced significant neurological recovery after surgery, but a worse preoperative neurological status was identified as an indicator affecting surgical outcomes by multivariate analysis (OR 10.77, 95% CI 2.88–40.36, p < 0.001). In addition, a larger lesion size was significantly associated with poor functional recovery in patients who had an unstable gait prior to surgery (8.6 ± 4.5 mm vs 3.5 ± 1.6 mm, p = 0.011). CONCLUSIONS Once a hemorrhage occurs, surgical intervention should be considered to avoid recurrence of the bleeding and further neurological injury. In contrast, if the patients with larger lesion presented with worse preoperative functional status, surgical intervention could have a risk for aggravating the functional deficiencies by damaging the thinning cord parenchyma. Conservative treatment may be selected if the lesion is small, but regular neurological examination by MRI is needed for assessment of a change in lesion size and for detection of functional deterioration.

Abstract
OBJECTIVE Optimal surgical strategies for intramedullary spinal cord cavernous malformations (ISCCMs) are not optimized and remain problematic. In this study the authors identify rational surgical strategies for ISCCMs and predictors of outcomes after resection. METHODS A single-center study was performed with 219 consecutive surgically treated patients who presented from 2002 to 2017 and were analyzed retrospectively. The American Spinal Injury Association (ASIA) Impairment Scale was used to evaluate neurological functions. Patient characteristics, surgical approaches, and immediate and long-term postoperative outcomes were identified. RESULTS The average ISCCM size was 10.5 mm. The spinal level affected was cervical in 24.8% of patients, thoracic in 73.4%, and lumbar in 1.8%. The locations of the lesions in the horizontal plane were 30.4% ventral, 41.6% dorsal, and 28.0% central. Of the 214 patients included in the cohort for operative evaluation, 62.6% had superficially located lesions, while 37.4% were embedded. Gross-total resection was achieved in 98.1% of patients. The immediate postoperative neurological condition worsened in 10.3% of the patients. Multivariate logistic regression identified mild preoperative function (p = 0.014, odds ratio [OR] 4.5, 95% confidence interval [CI] 1.4-14.8) and thoracolumbar-level lesions (p = 0.01, OR 15.7, 95% CI 1.9-130.2) as independent predictors of worsening. The mean follow-up duration in 187 patients was 45.9 months. Of these patients, 63.1% were stable, 33.2% improved, and 3.7% worsened. Favorable outcomes were observed in 86.1% of patients during long-term follow-up and were significantly associated with preoperative mild neurological and disability status (p = 0.000) and cervically located lesions (p = 0.009). The depths of the lesions were associated with worse long-term outcomes (p = 0.001), and performing myelotomy directly through a yellowish abnormal surface in moderate-depth lesions was an independent predictor of worsening (p = 0.023, OR 35.3, 95% CI 1.6-756.3). CONCLUSIONS Resection performed with an individualized surgical approach remains the primary therapeutic option in ISCCMs. Performing surgery in patients with mild symptoms at the thoracolumbar level and embedded located lesions requires more discretion.

Abstract
STUDY DESIGN A retrospective review of prospectively collected data. OBJECTIVE To confirm the feasibility of using anterior to dorsal root entry zone myelotomy (ADREZotomy), a new surgical approach, for the treatment of ventrolateral deep intramedullary spinal cord cavernous malformation (ISCCMs). SUMMARY OF BACKGROUND DATA Surgical removal of ventrolateral deep ISCCMs is highly risky and remains problematic. METHODS The authors performed a retrospective study exploring the surgical removal of ventrolateral intrinsic ISCCMs using ADREZotomy in 10 patients. The Frankel grading system was used to evaluate the patients' neurological function at the preoperative, postoperative and follow-up stages. American Spinal Injury Association Scale scores at the preoperative and postoperative were also obtained. The patient characteristics and surgical outcomes were analyzed. The indication, operative steps, complications, and anatomical basis of the myelotomies were described and discussed. RESULTS In total, nine (90%) patients presented with mild symptoms before surgery. Gross total resections were performed in all 10 patients. Immediately after surgery, the neurological function of eight (80.0%) patients remained the same. One patient improved and one (10%) patient worsened. There were no other immediate or delayed complications related to the surgical procedure. No decrease of total American Spinal Injury Association sensory scores was observed. The follow-up neurological function evaluation showed that two (20%) patients improved from a Frankel grade of D to E and eight (80.0%) patients were stable. No recurrences or other additional neurological deterioration was observed. CONCLUSION Surgical removal of ventrolateral deep ISCCMs can be feasible using proper surgical techniques. ADREZotomy is a minimally invasive technique for the removal of cervical and thoracic ventrolateral deep ISCCMs, without disrupting the important spinal cord tracts or the need to broadly expose bone.

Abstract
There is limited evidence to suggest that anterior approaches for the resection of ventral intramedullary lesions of the cervical spinal cord may result in superior neurological outcomes compared with those following more traditional posterior approaches. To the authors' knowledge, no report of an anterior approach to resect a ventral intramedullary capillary hemangioma exists in the literature. In the following paper, the case of a 75-year-old male who presented with progressive neck and left shoulder pain, weakness of the left hand, myelopathy, and gait imbalance is reported. Postcontrast T1-weighted MRI demonstrated a homogeneously enhancing intramedullary lesion with associated severe impingement of the cervical spinal cord at C-4. Following a C-4 corpectomy, intradural exposure revealed a vascular lesion that circumferentially enveloped the anterior spinal artery. Gross-total resection of the lesion was performed, followed by reconstruction of the corpectomy defect, without neurological deterioration. Pathology was consistent with capillary hemangioma. In this instance, the anterior approach helped to avoid unnecessary neural manipulation and allowed for early identification of normal proximal and distal segments of the anterior spinal artery, which facilitated safe dissection and gross-total removal.

Abstract
The majority of spinal cavernous angiomas (CAs) originate from the vertebral bodies with or without epidural space extension. Solitary epidural CAs are rare. In the present study, we retrospectively reviewed the records of 12 patients who underwent microsurgery for solitary spinal epidural CAs. All patients had performed pre- and postoperative magnetic resonance imaging. The patients were 7 females and 5 males with the mean age of 52.1 years. Two tumors were located in the cervicothoracic spine, nine in the thoracic spine and one in the lumbar spine, respectively. Solitary epidural CAs generally exhibited isointensity on T1-weighted images and hyperintesity on T2-weighted images. Contrast-enhanced T1-weighted images showed homogeneous markedly enhancement. Gross total resection (GTR) was achieved in 11 cases, and subtotal resection (STR) was achieved in 1 case. During an average follow up of 35.9 months, neurological function was improved in 11 patients and in one patient, preoperative status was maintained. No patient experienced tumor recurrence. These findings suggest that CAs should be considered in the differential diagnosis of spinal epidural lesions. Early surgery is advocated to prevent irreversible neurological deficits. When aggravated by a large amount of acute hemorrhage, neurological deterioration is usually acute and prompt surgical decompression is the optimal choice. Because of the excessive vascularity of CAs, en bloc resection is recommended. In addition, a good clinical outcome after GTR can be expected, and the risk of long-term recurrence is low.

Abstract
Aim We report the preoperative and postoperative findings and also neurological follow-up results from 10 spinal cavernoma patients treated in our clinic. Several representative cases are presented in terms of clinical features, imaging results, and surgical outcomes. Material and methods The data were retrospectively collected from patients' files in the hospital records and sorted with regards to clinical presentation, radiologic features, and operative findings. Patients received spinal MRI scans for the diagnosis of spinal cavernomas (SC) and postsurgical evaluation. Clinical presentation was evaluated via Ogilvy classification and symptoms were checked preoperatively and postoperatively at third month and first year using McCormick scale. Primary treatment was microsurgical operation aiming a gross total lesion resection. Results 10 spinal cavernoma patients between the ages 30 and 63 were treated. Six (60%) of the patients were diagnosed with cervical and four (40%) others were diagnosed with thoracic SC. Among the patient group, mean preoperative Ogilvy classification score was 2.3 ± 0.7.8 and McCormick score was 1.9 ± 0.7. There was no residual mass or relapse after surgery. One patient developed surgery-related left hemiparesis, which was normalized at 1 year follow-up. Conclusion Patients must be diagnosed with MRI since it is nowadays a gold standard. Preoperative and postoperative scores are important in evaluating the patients' condition and improvement. The results from our patient series also reinforce the notion that immediate surgery should be the preferred treatment method for cavernomas. Intraoperative neurophysiologic monitarization should assist the surgery in order to prevent complications. In conclusion, microsurgery is a gold standard method that we recommend for cases of cavernomas, which will not recur if gross total resection is achieved.

Abstract
PURPOSE OF REVIEW This study aims to review the current epidemiology and clinical management of patients with cavernous malformations (CM). RECENT FINDINGS Hemorrhage is the most feared complication and leads to morbidity in patients with CM. Multiple studies including three meta-analyses have provided useful estimates of hemorrhage risk, but have failed to identify a modifiable risk factor for prevention of cavernous malformation related hemorrhage. In treating the CM itself, surgical risk is weighed against the natural history. However, accumulating knowledge regarding the roles of CCM 1, 2, and 3 genes has led to the discovery of potential therapeutic targets. The risk of future hemorrhage in patients with CM is highest in those who have had previously clinical hemorrhages. Estimated risks are helpful in counseling patients and comparing to the risk of surgery. Future clinical trials of candidate medications are likely to target those patients with prior clinical hemorrhage in whom the surgical risk is deemed high.

Abstract
BACKGROUND Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital vascular disorder characterized by the classic triad of cutaneous nevi, venous varicosities, and osseous and soft tissue hypertrophy of the affected limb. Various vascular anomalies of the central nervous system have also been described in patients with KTWS. The English language literature to date contains 6 reports of associations between KTWS and spinal cord cavernous angioma (CA), but management of these patients has not been well described. CASE DESCRIPTION A 23-year-old woman was admitted to our institution with acute onset of leg weakness accompanied by upper back pain. Thoracic magnetic resonance imaging of the spinal cord showed a heterogeneous mass with a slit component at the T1-2 level. The patient underwent left hemilaminectomy followed by removal of the tumor, and her neurologic symptoms improved postoperatively. Pathologic examination showed the spinal lesion was characterized by hemosiderin deposition and thin-walled vascular channels surrounded by fibrous tissue. CONCLUSIONS This is the first report to provide a detailed pathologic description of the features of spinal CA in a patient with KTWS. Assessment of the clinical features and management of CA associated with KTWS are discussed. This syndrome is rare, and further experience in the treatment of these patients is needed. However, considering that the pathologic findings of spinal CA in patients with KTWS include the typical features of CA, the management of CA in patients with KTWS may be identical to management of isolated CA.

Abstract
Cavernous malformations are uncommon vascular lesions with an estimated prevalence of 0.5% in the general population. Intramedullary cavernous malformations (ICM) represent a rare subset of lesions, which account for approximately 5% of all cavernous malformations. The annual risk of hemorrhage in ICMs has been reported to range from 1.4 to 6.8%. Most patients are diagnosed with neurological dysfunction secondary to ICM hemorrhage and little is known about the inciting events that lead to hemorrhage. A few studies have suggested that minor and major trauma or even intense exertion may increase the risk of hemorrhage. We report the case of a 62-year-old male who developed progressive neurological deterioration following a motor vehicle accident. During work-up, an ICM was found at T4 and was surgically removed. At his 10-month follow-up, the patient had partially recovered, regaining motor strength in his right lower extremity, but had a persistent decrease in temperature and pinprick sensation on the left side starting at the T6 dermatome. We hypothesize that ICMs can rupture after high-energy impacts, such as the motor vehicle accident in our patient, and mechanical factors, such as trauma and stretching maneuvers, can play a role in the pathogenesis of ICM hemorrhage.

Abstract
We report a case of a 58-year-old Hispanic man who developed ascending paraparesis over several weeks secondary to recurrent hemorrhages and resulting in spinal cord ischemia from a low thoracic spinal cord cavernous malformation. The patient's deterioration was attributed to recurrent hemorrhage of a thoracic intramedullary cavernous malformation at T11 resulting in vascular congestion and spinal cord ischemia. The patient was found to have a heterozygous mutation on exon 13 of gene KRIT1, which was consistent with autosomal dominant familial cerebral cavernous malformations. Expedited surgical intervention potentially could have prevented this patient's progressive paraplegia.

Abstract
Cerebral cavernous malformations are vascular anomalies of the central nervous system characterized by clusters of enlarged, leaky capillaries. They are caused by loss-of-function mutations in KRIT1, CCM2, or PDCD10. The proteins encoded by these genes are involved in four partially interconnected signaling pathways that control angiogenesis and endothelial permeability. Cerebral cavernous malformations can occur sporadically, or as a familial autosomal dominant disorder (FCCM) with incomplete clinical and neuroradiological penetrance and great inter-individual variability. Although the clinical course is unpredictable, symptoms typically present during adult life and include headaches, focal neurological deficits, seizures, and potentially fatal stroke. In addition to neural lesions, extraneural cavernous malformations have been described in familial disease in several tissues, in particular the skin. We here present seven novel FCCM families with neurologic and cutaneous lesions. We review histopathological and clinical features and provide an update on the pathophysiology of cerebral cavernous malformations and associated cutaneous vascular lesions. © 2016 Wiley Periodicals, Inc.

Abstract
Introduction Cerebral cavernous malformation (CCM) is a vascular disorder characterized by the presence of central nervous system cavernomas. In familial forms, mutations in three genes (CCM1/KRIT1, CCM2/MGC4607 and CCM3/PDCD10) were identified. We describe a Portuguese family harboring a novel CCM1 mutation. Case Presentation The proband is a woman who at the age of 55 years started to have complex partial seizures and episodic headache. Although nothing was found during her neurological examination, brain MRI showed bilateral, supra- and infratentorial cavernomas. She had a sister who, at the age 61 years, suffered a tonic-clonic seizure. Neurological examination was normal and imaging investigation demonstrated a right frontal intracerebral hemorrhage and multiple cavernomas. In the following years, she suffered several complex partial seizures and had a new intracerebral hemorrhage located in the right temporal lobe. Genetic analysis was performed and a novel nucleotide substitution, i.e. c.1927C>T (p.Gln643*) within the exon 17 of the CCM1 gene, was detected in both sisters. The substitution encodes a stop codon, with a consequent truncated KRIT1 protein, therefore supporting its pathogenic role. Further affected family members were detected, suggesting an autosomal dominant pattern of inheritance. Conclusion We report a Portuguese family with a novel CCM1 (KRIT1) mutation – c.1927C>T (p.Gln643*). A better knowledge of the phenotype-genotype correlation is needed to improve the management of CCM patients.

Abstract
BACKGROUND Spinal cord cavernomas are rare, and progressive growth can lead to neurologic deterioration. Complete microsurgical resection using the OmniGuide® fiber-optic CO2 laser is safe, precise, and can prevent further neurological deterioration. We describe the process, risks, and benefits associated with this approach. METHODS Once the cavernoma is isolated, the CO2 laser enables the surgeon to incise and photocoagulate with the same instrument, increasing the accuracy and potentially reducing the procedure's duration. The spinal cord and surrounding tissue are protected from the laser by cerebrospinal fluid and cottonoid pledges. CONCLUSIONS The fiber-optic CO2 laser is safe and effective when resecting spinal cord cavernomas. Personal experience, coupled with recent literature, brings us to this conclusion.

Abstract
Object
Information pertaining to the natural history of intramedullary spinal cord cavernous malformations (ISCCMs) and patient outcomes after surgery is scarce. To evaluate factors associated with favorable outcomes for patients with surgically and conservatively managed ISCCMs, the authors performed a systematic review and metaanalysis of the literature. In addition, they included their single-center series of ISCCMs.
Methods
The authors searched MEDLINE, EMBASE, CINAHL, Google Scholar, and The Cochrane Library for studies published through June 2013 that reported cases of ISCCMs. Data from all eligible studies were used to examine the epidemiology, clinical features, and neurological outcomes of patients with surgically managed and conservatively treated ISCCMs. To evaluate several variables as predictors of favorable neurological outcomes, the authors conducted a meta-analysis of individual patient data and performed univariate and multivariate logistic regression analyses. Variables included patient age, patient sex, lesion spinal level, lesion size, cerebral cavernomas, family history of cavernous malformations, clinical course, presenting symptoms, treatment strategy (operative or conservative), symptom duration, surgical approach, spinal location, and extent of resection. In addition, they performed a meta-analysis to determine a pooled estimate of the annual hemorrhage rate of ISCCMs.
Results
Eligibility criteria were met by 40 studies, totaling 632 patients, including the authors' institutional series of 24 patients. Mean patient age was 39.1 years (range 2–80 years), and the male-to-female ratio was 1.1:1. Spinal levels of cavernomas were cervical (38%), cervicothoracic (2.4%), thoracic (55.2%), thoracolumbar (0.6%), lumbar (2.1%), and conus medullaris (1.7%). Average cavernoma size was 9.2 mm. Associated cerebral cavernomas occurred in 16.5% of patients, and a family history of cavernous malformation was found for 11.9% of evaluated patients. Clinical course was acute with stepwise progression for 45.4% of patients and slowly progressive for 54.6%. Symptoms were motor (60.5%), sensory (57.8%), pain (33.8%), bladder and/or bowel (23.6%), respiratory distress (0.5%), or absent (asymptomatic; 0.9%). The calculated pooled annual rate of hemorrhage was 2.1% (95% CI 1.3%–3.3%). Most (89.9%) patients underwent resection, and 10.1% underwent conservative management (observation). Outcomes were better for those who underwent resection than for those who underwent conservative management (OR 2.79, 95% CI 1.46–5.33, p = 0.002). A positive correlation with improved neurological outcomes was found for resection within 3 months of symptom onset (OR 2.11, 95% CI 1.31–3.41, p = 0.002), hemilaminectomy approach (OR 3.20, 95% CI 1.16–8.86, p = 0.03), and gross-total resection (OR 3.61, 95% CI 1.24–10.52, p = 0.02). Better outcomes were predicted by an acute clinical course (OR 1.72, 95% CI 1.10–2.68, p = 0.02) and motor symptoms (OR 1.76, 95% CI 1.08–2.86, p = 0.02); poor neurological recovery was predicted by sensory symptoms (OR 0.58, 95% CI 0.35–0.98, p = 0.04). Rates of neurological improvement after resection were no higher for patients with superficial ISCCMs than for those with deep-seated ISCCMs (OR 1.36, 95% CI 0.71–2.60, p = 0.36).
Conclusions
Intramedullary spinal cord cavernous malformations tend to be clinically progressive. The authors' findings support an operative management plan for patients with a symptomatic ISCCM. Surgical goals include gross-total resection through a more minimally invasive hemilaminectomy approach within 3 months of presentation.

Abstract
Introduction Cavernous angiomas of the spinal cord are rare vascular malformations, which account for approximately 5 to 12 percent of spinal cord vascular lesions. They usually originate in the vertebrae, with occasional extension into the extradural space, and intramedullary cavernomas, even if reported in the literature, are very rare. Case presentation We report the case of a 34-year-old Caucasian woman affected by a thoracic intramedullary cavernous angioma. Our patient complained of 10-day history of acute dorsal pain, progressive weakness of both lower extremities, worse on the right side, a ‘pins and needles’ sensation in the abdominal region and bladder dysfunction. Magnetic resonance imaging showed, at D5 level, a vascular malformation, which was not documented at spinal angiography. Our patient underwent surgical treatment with total removal of the lesion and her symptoms gradually improved. A histological examination revealed the typical features of a cavernous angioma. Conclusions Intramedullary cavernous angioma is a rare lesion that should be diagnosed early and surgically treated before rebleeding or enlargement of the lesion can occur.

Abstract
Object
Intramedullary spinal cord cavernous malformations (CMs), once thought to be extremely rare, have been diagnosed more frequently since the advent of MR imaging. In the literature, however, only a few studies include more than 10 cases. The aim of this study was to discuss the clinical presentation of intramedullary spinal cord CMs and the outcome of microsurgery for these histologically benign but clinically progressive lesions.
Methods
The authors retrospectively reviewed the records of 20 patients who underwent microsurgery for intramedullary spinal cord CMs. All patients had undergone pre- and postoperative MR imaging, and they were all treated using microsurgical resection. The diagnosis of spinal cord CMs was based on pathological criteria. The pre- and postoperative neurological states of the patients were classified according to the McCormick scale and Frankel scale. The microsurgical outcomes are presented and discussed.
Results
In most cases, CMs can be diagnosed on the basis of MR imaging findings, since these lesions have certain characteristic imaging patterns. Patients with intramedullary spinal cord CMs may present with either a rapid, acute onset of symptoms or slow, progressive neurological decline. The CMs in 19 of 20 patients in this series were totally resected, and most patients neurologically improved postoperatively. As previously reported, the authors confirm that the treatment of choice for symptomatic intramedullary CMs is total removal of the lesion to avoid recurrence and the possibility of further hemorrhage.
Conclusions
This study has defined the clinical features of symptomatic intramedullary spinal cord CMs. Surgery is the mainstay treatment. Surgical outcome is associated with low mortality with a high probability of functional recovery, especially when symptoms are not severe and are of relatively recent onset.

Abstract
The management of brain and spinal cavernomas includes two main options: (i) conservative treatment or (ii) surgical removal. Clinical experience related to cavernoma patients falls into four major categories: the surgical or conservative treatment of incidental or symptomatic cavernomas. In many patients, cavernomas exist as fairly benign lesions, frequently remaining clinically silent for life. This observation argues against the active treatment of all cavernoma patients; rather for the meticulous selection of only those more likely to benefit from surgery. Thus, the most crucial task in successful management of cavernomas is appropriate patient selection. In this review, we present our institutional experience on cavernoma management supplemented with data from the literature.

Abstract
Object
The authors conducted a study to assess the clinical pattern, radiological features, therapeutic strategies, and long-term outcomes in patients with intramedullary spinal cord cavernomas (ISCCs) based on a large case series.
Methods
This retrospective study identified 96 patients (60 males, 36 females) surgically (81 cases) or conservatively (15 cases) treated for ISCCs between May 1993 and November 2007. Each diagnosis was based on MR imaging and spinal angiography evidence. For all surgically treated patients, the diagnosis was verified pathologically. The neurological outcomes pre- and postoperatively, as well as long-term follow-up, were assessed using the Aminoff-Logue Disability Scale.
Results
The mean age at the onset of symptoms was 34.5 years (range 9–80 years). Of the lesions, 68 (71%) were located in the thoracic spine, 25 (26%) in the cervical spine, and only 3 (3%) in the lumbar spine. The median symptom duration was 19.7 months. The clinical behavior of the lesion was a slow progression in 73 cases and an acute decline in 23 cases. Long-term follow-up data (mean 45.8 months, range 10–183 months) were available for 75 patients (64 surgical cases and 11 conservative cases). In the surgical group, a complete resection was achieved in 60 patients, and incomplete resection was detected in 4 patients after operation. At the end of the follow-up period in the operative group, 23 patients (36%) improved, 35 (55%) remained unchanged, and 6 (9%) worsened. In the nonoperative group, 5 patients improved, 6 patients remained unchanged, and none worsened.
Conclusions
For differential diagnosis, spinal angiography was necessary in some cases. For most symptomatic lesions, complete microsurgical resection of the symptomatic ISCC is safe and prevents rebleeding and further neurological deterioration. However, in patients whose lesions were small and located ventrally in the spinal cord, one can also opt for a rigorous follow-up, considering the high surgical risk.

Abstract
PURPOSE We demonstrate clinical features, therapy and outcome of 14 patients with symptomatic spinal cavernous malformations (CM). METHODS We retrospectively reviewed all patients who underwent microsurgical treatment of symptomatic spinal CM during the last decade in our department through an analysis of our database. RESULTS We analyzed the data of 14 patients (11 females, 3 males) with symptomatic spinal CM in a range of 16-77 years (mean age 47.8 years). Seven patients (50%) experienced significant improvement of their symptoms rapidly after surgery. The remaining seven patients presented new non pre-existing complaints, which improved gradually with a favourable outcome at the last follow-up examination in six cases. CONCLUSION Microsurgical treatment under perioperative electrophysiological monitoring is justified to prevent severe neurofunctional deterioration in symptomatic spinal CM. Although some of the patients deteriorate after surgery, the symptoms are rapidly declining with a favourable outcome in majority of them.

Abstract
OBJECT The management of intramedullary spinal cord cavernous malformations (CMs) is controversial. At Barrow Neurological Institute, the authors selectively offer surgical treatment for symptomatic spinal cord CMs. The purpose of this paper is to review the clinical outcomes in patients after resection of these lesions based on a single-center experience over a 25-year period. METHODS The records of 80 patients who underwent resection of pathologically confirmed spinal cord CMs from January 1985 to May 2010 were analyzed retrospectively. Preoperative clinical status and imaging findings were evaluated as well as immediate and long-term postoperative outcomes. RESULTS Compared with their preoperative Frankel grade, 11% of patients were worse, 83% were the same, and 6% improved immediately after surgery. At a mean follow-up interval of 5 years, 10% of patients were worse, 68% were the same, and 23% were improved compared with their preoperative status. Five percent of patients underwent reoperation for resection of a symptomatic residual or recurrent lesion. Immediate complications were encountered in 6% of patients, including CSF leakage and deep venous thrombosis. Long-term complications were encountered in 14% of patients and included kyphotic deformity, stenosis, and spinal cord tethering. A significant correlation was found between long-term outcome and anteroposterior length of the lesion (p = 0.01). CONCLUSIONS The resection of intramedullary spinal cord CMs can be achieved with good long-term outcomes and an acceptable risk of immediate or delayed complications.

Abstract
Although originally the subject of rare case reports, intramedullary spinal cord cavernous malformations (CMs) have recently surfaced in an increasing number of case series and natural history reports in the literature. The authors reviewed 27 publications with 352 patients to consolidate modern epidemiological, natural history, and clinical and surgical data to facilitate decision making when managing these challenging vascular malformations. The mean age at presentation was 42 years without a sex predilection. Thirty-eight percent of the cases were cervical, 57% thoracic, 4% lumbar, and 1% unspecified location. Nine percent of the patients had a family history of CNS CMs. Twenty-seven percent of the patients had an associated cranial CM. On presentation 63% of the patients had motor deficits, 65% had sensory deficits, 27% had pain, and 11% had bowel or bladder dysfunction. Presentation was acute in 30%, recurrent in 16%, and progressive in 54% of cases. An overall annual hemorrhage rate was calculated as 2.5% for 92 patients followed up for a total of 2571 patient-years. Across 24 reviewed surgical series, a 91% complete resection rate was found. Transient morbidity was seen in 36% of cases. Sixty-one percent of patients improved, 27% were unchanged, and 12% were worse at the long-term follow-up. Using this information, the authors review surgical nuances in treating these lesions and propose a management algorithm.

Abstract
Object
Spinal cavernomas are rare, but can cause significant neurological deficits due to mass effect and extralesional hemorrhage. The authors present their results of microsurgical treatment of 14 consecutive patients with spinal cavernoma, and review the literature.
Methods
Of the 376 patients with cavernomas of the CNS treated at Helsinki University Central Hospital (a catchment area close to 2 million inhabitants) between January 1980 and June 2009, 14 (4%) had a spinal cavernoma. The authors reexamined and analyzed the patient files and images retrospectively. Median patient age at presentation was 45 years (range 20–57 years). The female/male ratio was equal. Median duration of symptoms before admission to the department was 12 months (range 0.1–168 months). Patients suffered from sensorimotor paresis, radicular pain, or neurogenic micturition disorders in different combinations or separately. Hemorrhage had occurred in 7 patients (50%) before surgery. In 9 patients (64%) the cavernoma was intramedullary, in 4 (29%) extradural, and in 1 intradural extramedullary. On MR imaging, 6 patients (43%) had a cavernoma in the cervical region, 7 (50%) in the thoracic region, and 1 (7%) in the lumbar region.
Results
Postoperatively, patients were followed up for a median of 3 years (range 1–10 years). At follow-up, 13 patients (93%) experienced significant improvement in motor ability after surgery, and all patients were able to walk with or without aid. Ten of the 11 patients with pain syndrome (91%) showed significant pain relief without recurrence. Micturition disorder was noted in 6 patients (43%) at follow-up, but in 5 the condition had existed before surgery. No patient improved in bladder function after surgery, and 1 patient developed micturition dysfunction postoperatively.
Conclusions
Microsurgical removal of spinal cavernomas alleviates sensorimotor deficits and pain caused by mass effect and hemorrhage. However, bladder dysfunction remains unchanged after surgery.

Abstract
INTRODUCTION Less than 20 children with intramedullary cavernoma (ImC) have been reported in the English literature; however, cases with an unfavorable outcome may be underreported. Whereas these are predominantly boys, we report two girls who presented with hematomyelia (one cervical, one thoracic) and an acute, severe neurological deficit. CASE MATERIAL A 10-year-old girl complaining about lower thoracic pain for several days suddenly developed lower body dysesthesias and paraparesis. Magnetic resonance (MR) demonstrated hematomyelia (T8-T11), intramedullary edema (T6-L1), and an ImC at T9-T10. Within an hour, she progressed to paraplegia and was therefore operated immediately. She slowly recovered regaining independent ambulation and continence. MR after 2 years shows no recurrence. A 7-year-old girl suddenly developed cervicalgia and paresis of her left arm and leg. MR demonstrated hematomyelia and an ImC at C4-C6. She gradually recovered with minimal residual deficit at 3 months and was subsequently operated uneventfully. Multiple cerebral cavernomas and a familial autosomal cavernous malformation syndrome were diagnosed. The following 1.5 years, she complained of intermittent cervicalgia and left brachial dysesthesias, with MR suggesting active residual cavernoma. Interestingly, her complaints gradually disappeared, and she is currently asymptomatic. MR after 3.5 years shows minimal cord swelling no longer suggesting active residual cavernoma. CONCLUSION With adequate surgical treatment either in the acute phase in case of dramatic deterioration or after clinical recuperation, prognosis of symptomatic ImC may be surprisingly good. However, subtotally resected lesions and/or syndromal cases may recur, requiring further treatment. Definitive answers await more cases with longer follow-up.
