Abstract
Spinal cord cavernous malformation is a rare and uncommon vascular malformation, it may remain asymptomatic for a long period or manifest as a sudden or gradual change in spinal cord functioning. The diagnosis relies essentially on magnetic resonance imaging (MRI). Surgery constitutes the majority of management with all the complications that can occur during and after surgery. We report a case of intramedullary cavernoma of a 12-year-old patient admitted for acute paraparesia with bowel and bladder dysfunction. MRI revealed 2 intramedullary cavernomas at T6-T7 and T11-T12. Through this case report, we discuss the clinical and radiological characteristics of this unusual intramedullary malformation.

Abstract
Objective Spinal cord cavernous malformation (SCCM) is a rare vascular lesion, and the treatment strategy remains controversial at present. The goal of this retrospective study was to analyze the surgical outcomes of the SCCM and to find more appropriate treatment strategies for a better prognosis. Method A retrospective review of 98 patients with SCCM from 2009 to 2018 was conducted at the neurosurgical center of our hospital. Neurological function was assessed using the American Spinal Injury Association (ASIA) impairment scale. Clinical features were analyzed using the multivariable logistic regression. Results Ninety-eight patients with SCCM were included, of whom 36% were female and 64% male. The mean age was 41.6 years; and family history was reported in 8% of patients. Definite hemorrhage was found in 6%. Before surgery, the neurological status was Grade A in 2%, Grade B in 2%, Grade C in 12%, Grade D in 54%, and Grade E in 30% of the patients. 83% (81/98) patients had long-term follow-up, of whom, 42% had improved, 51% were stable and 7% had deteriorated. Patients with dorsal or superficial lesions showed better improvement than those with ventral or lateral deep lesions. Those with symptoms lasting less than three months had higher rates of improvement than those with symptoms lasting more than three months. However, there was no significant difference in prognosis between hemilaminectomy and laminectomy. Conclusion These results suggest that surgical strategies should be preferred for severe symptomatic SCCMs if total resection can be achieved, thereby avoiding the risk of severe complications with subsequent lesion hemorrhage. Earlier (usually within 3 months of symptom duration) surgical resection generally may lead to a better prognosis. For ventral or lateral deep SCCMs, the surgical strategy should be considered more carefully.

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
We describe Natural history, clinical and surgical management of cavernous malformation of the brain and spinal cord. Decision-making for treatment of cavernous malformations cannot ignore their natural history and risk of bleeding, which is different depending on the location. Surgical morbidity also depends on the position of the lesion. We performed a review of hemorrhage risk and clinical assessment of superficial and deep supratentorial, brainstem and intramedullary cavernous malformations.

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
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
A 2-month-old infant presented with a cervical intramedullary spinal cord cavernous angioma manifesting as left hemiparesis caused by hematomyelia. Osteoplastic laminotomy of the cervical spine was carried out with subsequent microsurgical excision of the intramedullary spinal cord cavernous angioma. Magnetic resonance imaging revealed no residual tumor. At 25 months after the surgery, she presented no neurological deficit without recurrence and cervical deformity. This case of infantile intramedullary spinal cord cavernous angioma presenting with cervical hematomyelia shows osteoplastic laminotomy of the cervical spine might be helpful to prevent consequent cervical deformity in pediatric cases.

Abstract
A 41-year-old woman presented with a rare cervical intramedullary cavernous angioma manifesting as acute paralysis in her left upper extremity. Magnetic resonance imaging revealed hematomyelia. Laminectomy (C2-C7) was performed, followed by posterior midline myelotomy and removal of the intramedullary hematoma and the tumor. She showed marked improvement after the surgery. However, 3 years and 10 months later the patient showed slight intramedullary bleeding located ventrally at the same level. Anterior approach with corpectomy was performed. Complete removal of the tumor was attained and salvage surgery was performed. Postoperative stabilization was achieved with excellent clinical outcome. The anterior approach is useful method as a salvage surgery for ventrally located cavernous angioma.

Abstract
Although there has been considerable experience with anterior approaches to ventral intradural, extramedullary, and pial-based spinal lesions, there is no information in the literature regarding the safety and feasibility of the resection of an intramedullary tumor via an anterior approach. The authors report on the gross-total resection of an intramedullary cervical pilocytic astrocytoma via a C-7 corpectomy and anterior myelotomy. The surgery proceeded without complication, and postoperatively the patient maintained the preoperative deficit of mild unilateral hand weakness but had no sensory deficits. Follow-up MR imaging at 6 months showed gross-total macroscopic resection. Selected intramedullary tumors can be safely removed via an anterior approach. This approach avoids the typical sensory dysfunction associated with posterior midline myelotomy.

Abstract
This article reviews the pathology, clinical course and management of cavernous angiomas in the brain stem and spinal cord. Both lesions have been diagnosed with increasing frequency as a result of magnetic resonance image scanning. Brain stem lesions tend to present dramatically; their treatment remains microsurgical excision despite some studies that have looked at the use of radiosurgery. Spinal lesions are either extra-, or more commonly, intramedullary. Intramedullary cavernomas present with a wide spectrum of symptoms ranging from acute haematomyelia to presentations that mimic demylelinating conditions; extramedullary cavernous angiomas tend to produce radicular symptoms or subarachnoid haemorrhage. Both are treated by microsurgical excision.

Abstract
OBJECT The authors present their experience with the 17th pediatric intramedullary cavernoma reported in English literature. METHODS The patient firstly underwent surgery for a left frontal cavernoma when he was 2 years old. Also the child's mother was operated for a C2-C3 intramedullary cavernoma. He grew up normally and the radiological follow-up was negative for other brainstem cavernous malformations. When he was 11 years old he complained a worsening tetraparesis. A cerebral and spinal magnetic resonance (MR) imaging revealed the presence of a C1 intramedullary cavernoma and a pontine cavernoma. He underwent surgery for the cervical lesion, which was completely removed. The postoperative course was regular with a total recovery from the neurological deficit. The boy underwent a radiological follow-up, monitoring the pontine lesion, which spontaneously regressed when he was 19 years old. CONCLUSION The rarity of the pediatric intramedullary cavernoma, the familial occurrence, and the spontaneous regression of the pontine cavernoma make this case very peculiar.

Abstract
Although intramedullary spinal cord cavernous malformations are now well described, there have been, to our knowledge, no prior reports focusing on presentation after trauma. We report a patient with a thoracic intramedullary cavernous malformation presenting with hematomyelia and acute neurologic deterioration after spinal chiropractic manipulation. A review of previously published case reports then identifies additional cases of deterioration after spinal cord trauma or exertion. Traumatic injury and exertion may be uncommon but real causes of hematomyelia in intramedullary cavernous malformations of the spinal cord. The frequency of such presentations is estimated to be 1.37% to 4.79%.

Abstract
OBJECTIVE The presentation and natural history of untreated, symptomatic intramedullary spinal cavernomas at our institution were analyzed. The objective is to provide additional information regarding the natural history of conservatively managed, symptomatic, intramedullary spinal cord cavernous malformations. METHODS The medical records of patients treated in our institution between 1989 and 2002 were reviewed to identify those with intramedullary cavernomas. The medical, radiological, surgical, and pathological records from these patients were retrospectively reviewed and analyzed. RESULTS Fourteen patients were included in the study. The mean age at presentation was 42 years. Four lesions (29%) were located in the cervical region and 10 lesions (71%) were present in the thoracolumbar spinal cord. All patients were symptomatic at the time of presentation. In this cohort of 14 patients, 10 patients (71%) were conservatively managed. For these patients, the mean duration of symptoms before presentation was 10 months. The mean duration of follow-up from the time of presentation was 80 months. The median McCormick grade for conservatively treated patients at presentation was II. During this period, none of the conservatively managed patients had an acute intramedullary bleed. In nine patients, the McCormick grade at the last follow-up evaluation was the same as or better than their score at presentation. Four patients (29%) were treated surgically. The mean duration of symptoms before presentation was 33 months. The mean duration of follow-up from the time of presentation was 42 months. In two surgical patients, the McCormick grade at the last follow-up evaluation remained unchanged compared with their score at presentation, whereas the McCormick grade improved in one patient and deteriorated in another patient. CONCLUSION This cohort of conservatively managed patients with symptomatic, intramedullary spinal cord cavernomas was clinically stable throughout the follow-up period. In this series, patients harboring symptomatic spinal cord cavernous malformation did not have significant, permanent neurological decline during the follow-up period when treated with the conservative approach of observation. This data provides additional information for determining the appropriate treatment strategy for patients with intramedullary spinal cavernomas.

Abstract
INTRODUCTION The prevalence of cerebral cavernomas is about 0.5% in the general population. In contrast, spinal cord cavernomas are considered as rare. The objective of this study was to determine the natural history of spinal cord cavernomas in a multicentric study. METHODS Clinical and neuroradiological findings were retrospectively collected. Diagnosis was based on pathological criteria or magnetic resonance (MR) findings. RESULTS Fifty-three patients were included (26 males, 27 females). Mean age at onset of symptoms was 40.2 years (range: 11-80). Initial symptoms were progressive (32) and acute myelopathy (20). One patient was asymptomatic. Clinical symptoms were related to spinal cord compression (24) and hematomyelia (19). Cavernoma location was dorsal (41) and cervical (12.). MR findings consisted of hyperintense signal on T1 and T2 sequences (19 cases), mixed hyperintense and hypointense signal (33 cases), and hypointense signal on T1 and T2 sequences in 1 case. Mean size was 16.3 mm (range: 3-54). Forty patients underwent surgical resection. Improvement was observed in 20 patients and worsening of neurological symptoms in 11. Length of follow up was 7.1 years. At the end of the study, 26 patients were autonomous, 18 handicapped and 1 bedridden. CONCLUSION This study provided precise data on the clinical and MR patterns of these lesions. The natural history is associated with a higher risk of hemorrhage recurrence, but is favorable in many operated patients. Microsurgery is the treatment of choice for most of these lesions.

Abstract
Intradural spinal-cord tumours are an uncommon but important consideration in the differential diagnosis of patients with back pain, radicular pain, sensorimotor deficits, or sphincter dysfunction. Intradural spinal tumours can be divided into intramedullary and extramedullary spinal-cord tumours on the basis of their anatomical relation to the spinal parenchyma. The heterogeneous cell composition of the intradural compartment allows the formation of neoplasms, arising from glial cells, neurons, and cells of spinal vasculature. Additionally, developmental tumours, metastases, and intradural extension of extradural tumours are represented. In this Review, we discuss the published work on intradural spinal-cord tumours in terms of epidemiological, radiographic, and histological characteristics. Surgical and adjuvant treatment strategies are also reviewed.

Abstract
Object
Intramedullary cavernous malformations (CMs) account for approximately 5% of all intraspinal lesions. The purpose of this study was to define the spectrum of presentation for spinal intramedullary CMs and the results of microsurgery for these benign but clinically progressive lesions.
Methods
Retrospective chart review was performed in 26 patients with histologically diagnosed CMs. All patients had undergone preoperative magnetic resonance (MR) imaging studies. All patients were treated with a laminectomy and microsurgical resection of the malformation.
Conclusions
The MR imaging findings are diagnostic for intramedullary CMs; these lesions abut a pial surface and have a characteristic imaging pattern. Spinal intramedullary CMs present with either an acute onset of neurological compromise or a slowly progressive neurological decline. Acute neurological decline occurs secondary to hemorrhage inside the spinal cord. Chronic progressive myelopathy occurs due to microhemorrhages and resulting gliotic reaction to blood products. Surgery and total removal of the lesion tends to halt progression of symptoms.

Abstract
Abstract
OBJECTIVE:
We report three cases with ventral cervical intramedullary cavernous angiomas. An anterolateral partial vertebrectomy was performed to surgically approach and successfully resect these lesions.
MATERIALS AND METHODS:
All three patients presented with numbness in the upper extremities and investigation revealed a cavernous angioma on the ventral aspect of the spinal cord in each case. The lesion was exposed by an anterolateral partial vertebrectomy in all cases. Postoperative stabilization was achieved by using autografted iliac bone in all patients. In two patients, locking screws and plates were also used.
RESULTS:
Complete resection of the cavernous angioma was performed in all patients. There was symptomatic relief in all cases, and there was no postoperative morbidity.
CONCLUSION:
Anterolateral partial vertebrectomy provides direct exposure and is probably an ideal approach for selected cases with ventrally located intramedullary cavernous angiomas.

Abstract
Abstract
OBJECTIVE:
To determine the short- and long-term effects of surgical resection of intramedullary spinal cavernous malformations on preoperative pain.
METHODS:
Between 1988 and 2003, 53 intramedullary spinal cavernous malformations were surgically managed. A retrospective analysis of this cohort revealed 23 (43%) patients who presented with pain as a clinically relevant feature. Long-term evaluation of pain outcomes was available in 21 patients. Pain outcomes were characterized as improved, unchanged, or worse compared with preoperative and immediate postoperative status.
RESULTS:
Seven patients presented with radiculopathy, 12 with central pain, and four with both. Immediately after surgery, pain symptoms improved in 18 (78%) patients, were unchanged in 5 (22%), and were worse in none compared with the patients' preoperative status (n = 23). During the follow-up period, 11 (52%) patients improved, nine (43%) remained at their preoperative baseline, and one (5%) was worse compared with their preoperative levels of pain. The difference in postoperative and long-term pain status was statistically significant (P = 0.031).
CONCLUSION:
The surgical efficacy for improving pain related to intramedullary spinal cavernous malformations may be worse than implied in the literature. Although pain relief immediately after surgery is good, we found that recurrence is common and that only approximately 50% of patients report long-term benefit. Despite the significant limitations of this retrospective study, these data may serve as a guide when counseling patients preoperatively to help them to maintain realistic expectations about outcomes.

Abstract
The authors describe seven cases of extradural spinal cavernous angioma. Although cavernoma itself is not rare, the extradural spinal localization is uncommon and makes preoperative differential diagnosis difficult. Routine MRI investigation has aided neurosurgeons in evaluating the true incidence of these vascular malformations, which was understimated in the past. The data published so far have not entirely clarified the treatment of choice for these lesions. Considering their rarity in this site, their presenting symptoms and the difficulties involved in neuroradiological diagnosis, the authors discuss the role of surgery as the principal form of treatment and review the relevant literature. Seven patients (4 male, 3 female) were admitted to our Institute of Neurosurgery between 1992 and 2004, with a 5-6 month history (range=2-365 days) of low back pain or radicular pain, sometimes associated with paresthesia. All patients had a CT scan, as well as MRI with gadolinium when possible, which detected an extradural roundish lesion: differential diagnosis was very difficult, especially between neurinoma and cavernoma. Treatment was always surgical and resection of the lesion radical. Postoperatively, all patients presented complete regression of clinical symptoms. In all cases histological diagnosis was cavernous angioma. Postoperative MRI with gadolinium or CT scan with IV contrast, performed before discharge, confirmed radical removal of the vascular malformation in all cases. Our experience confirms that surgery should be the treatment of choice for these lesions, in view of both their tendency to bleed and their straightforward surgical removal.

Abstract
Abstract
OBJECTIVE AND IMPORTANCE:
This is the first reported case of histologically proven multiple spinal cavernous malformations (CMs) associated with previous irradiation. There are only two cases reported in the literature of solitary spinal CM after irradiation. In addition, the lesions in our patient had an atypical magnetic resonance imaging appearance mimicking intraspinal drop metastasis.
CLINICAL PRESENTATION:
A 33-year-old man had an incidental finding of multiple enhancing intraspinal lesions as revealed by magnetic resonance imaging during staging tests for hepatocellular carcinoma. He had a history of Wilms' tumor at a young age with irradiation to the abdomen and pelvis. His family history included a paternal cousin with multiple cerebral CMs. The diagnosis of spinal drop metastasis was made, and further intervention was undertaken for confirmation.
INTERVENTION:
The patient underwent a lumbar laminectomy with durotomy and excision of two of the lesions. Macroscopic analysis revealed mulberry-like appearance with nerve root involvement, and pathological analysis confirmed the diagnosis of CM. Genetic testing of the patient and his affected cousin was negative for the CCM1 gene.
CONCLUSION:
The occurrence of multiple spinal lesions in the context of known neoplasia indicates a diagnosis of metastasis. Spinal CMs were not suspected preoperatively because of the atypical appearance revealed by magnetic resonance imaging scans, with uniform contrast enhancement and absence of hemosiderin rim. This case report is discussed relative to previous literature regarding radiation-induced CMs and other known causes of the disease.

Abstract
O hemangioma cavernoso intramedular é anomalia vascular de baixo fluxo, curável através de ressecção cirúrgica. Entretanto, se não forem instituídos o diagnóstico precoce e a terapêutica adequada, pode levar à graves sequelas neurológicas. É extremamente raro a ocorrência de um angioma cavernoso intramedular. É relatado o caso de uma paciente de 33 anos, com um angioma cavernoso intramedular no nível de T6 - T7, que apresentava quadro clínico de compressão medular lenta e progressiva, com piora recente importante. A ressonância magnética da coluna torácica demonstrou, entre a sexta e a sétima vértebras dorsais, lesão expansiva intramedular que se apresentava hipointensa em T1 e discretamente hiperintensa em T2, com pequeno halo hipointenso à sua volta nas duas sequências. A paciente foi submetida a tratamento cirúrgico tardio e não apresentou recuperação neurológica. Os achados clínicos, de imagem e a importância de instituir precocemente o tratamento adequado são analisados e discutidos.

Abstract
There is a growing body of evidence in the literature suggesting that cavernous malformations of the central nervous system may develop after neuraxis irradiation. The authors discuss the case of a 17-year-old man who presented with progressive back pain and myelopathy 13 years after undergoing craniospinal irradiation for a posterior fossa medulloblastoma. Spinal magnetic resonance (MR) imaging, performed at the time of his initial presentation with a medulloblastoma, demonstrated no evidence of a malformation. Imaging studies and evaluation of cerebrospinal fluid revealed no evidence of recurrence or dissemination. Spinal MR imaging demonstrated an extensive lesion in the thoracic spine with an associated syrinx suggestive of a cavernous malformation. A thoracic laminectomy was performed and the malformation was successfully resected. Pathological examination confirmed the diagnosis. The patient did well after surgery and was ambulating without assistance 6 weeks later. To the best of the authors' knowledge, this is the second reported case in the literature and the first in the young adult age group suggesting the de novo development of cavernous malformations in the spinal cord after radiotherapy. An increased awareness of these lesions and close follow-up examination are recommended in this setting.

Abstract
STUDY DESIGN A retrospective analysis of a large single institution pediatric intramedullary tumor database. The database was searched for all pediatric intramedullary cavernous malformations. OBJECTIVES To review the authors' experience with three pediatric intramedullary cavernous malformations, review the previous literature, and discuss the surgical management for these rare lesions. SUMMARY OF BACKGROUND DATA Cavernous malformations can occur throughout the central nervous system; however, the intramedullary spinal cord is a rare location. More recent estimates indicate that cavernous malformations constitute 5% of all vascular malformations. There is no series that reports the management of pediatric intramedullary cavernous malformations. METHODS There were 181 pediatric intramedullary lesions in the tumor database. A review revealed three children with a mean age of 13.3 years (range, 8-19 years) with intramedullary cavernous malformations. All these children presented with an acute motor deficit that prompted radiographic imaging and diagnosis. All the children underwent laminectomy and gross total removal of the lesion. All the malformations abutted the dorsal pial surface and created a blue discoloration, which was evident after opening the dura. RESULTS Approximately 10% of all intramedullary cavernous malformations present in the pediatric population. Pediatric lesions, unlike those in adults, have an acute presentation, and the lesions are typically found in the cervical region. The surgical removal of these malformations results in a good functional outcome. The entire neuraxis should be screened because there is a high incidence of multiple lesions. CONCLUSIONS The surgical removal of these malformations results in a good functional outcome. The entire neuraxis should be screened because there is a high incidence of multiple lesions.

Abstract
OBJECT Improved neuroimaging techniques have led to an increase in the reported cases of intramedullary cavernomas. The purpose of this study was to define the spectrum of presenting signs and symptoms in patients with spinal intramedullary cavernomas and to analyze the role of surgery as a treatment for these lesions. METHODS The authors reviewed the charts of 16 patients who underwent surgery for spinal intramedullary cavernomas. All patients underwent preoperative magnetic resonance imaging studies. Cavernomas represented 14 (5.0%) of 280 intramedullary lesions found in adults and two (1.1%) of 181 intramedullary lesions found in pediatric cases. A posterior laminectomy and surgical resection of the malformation were performed in all 16 patients. CONCLUSIONS Magnetic resonance imaging is virtually diagnostic for spinal cavernoma lesions. Patients with spinal intramedullary cavernomas presented with either an acute onset of neurological compromise or a slowly progressive neurological decline. Acute neurological decline occurs secondary to hemorrhage within the spinal cord. Chronic progressive myelopathy occurs due to microhemorrhages and the resulting gliotic reaction to hemorrhagic products. There is no evidence that cavernomas increase in size. The rate of rebleeding is unknown, but spinal cavernomas appear to be clinically more aggressive than cranial cavernomas, probably because the spinal cord is less tolerant of mass lesions. Complete surgical removal of the cavernoma was possible in 15 of 16 of the authors' cases.

Abstract
Analysis of recent reports has suggested that cavernous malformations (CMs) of the brain may have an acquired pathogenesis and a dynamic pathophysiological composition, with documented appearance of new lesions in familial cases and following radiotherapy. The authors report the first case of demonstrated de novo formation of an intramedullary CM following spinal radiation therapy. A 17 year-old boy presented with diabetes insipidus and delayed puberty. Evaluation of endocrine levels revealed hypopituitarism, and magnetic resonance (MR) imaging demonstrated an infundibular mass. The patient underwent a pterional craniotomy and removal of an infundibular germinoma. The MR image of the spine demonstrated normal results. The patient received craniospinal radiation therapy and did well. He presented 5 years later with acute onset of back pain, lower-extremity weakness and numbness, and difficulty with urination. An MR image obtained of the spine revealed an intramedullary T-7 lesion; its signal characteristics were consistent with a CM. The patient was initially managed conservatively but developed progressive myelopathy and partial Brown-Séquard syndrome. Although he received high-dose steroids and bed rest, his symptoms worsened. He underwent a costotransversectomy and excision of a hemorrhagic vascular lesion via an anterolateral myelotomy. Pathological examination confirmed features of a CM. The patient has done well and was walking without assistance within 4 weeks of surgery. De novo genesis of CMs may be associated with prior radiation therapy to the spinal cord.

Abstract
BACKGROUND Intramedullary cavernomas are rare lesions usually operated on via a posterior approach and myelotomy. CASE REPORT A 42-year-old woman progressively developed a tetraplegia with sphincter disturbances over a period of 26 years. Magnetic resonance imaging showed a cervical intramedullary cavernoma with an extramedullary anterolateral exophytic portion. To avoid myelotomy, this lesion was approached directly via its anterior exophytic portion. Through a cervical anterolateral approach, the vertebral body of C4 and the intervertebral discs were obliquely drilled out. The posterior longitudinal ligament and the dura mater were opened. The exophytic portion was coagulated and the intramedullary portion was completely excised. The dura mater was closed and a bone graft was inserted between C3 and C5 and secured with a plate. RESULTS After transient worsening, upper limb weakness improved from its preoperative status but paraparesis persisted after a follow-up of 12 months. The sphincter disturbances disappeared. CONCLUSIONS The anterolateral approach combined with oblique corpectomy may be an appropriate technique in case of anterior intramedullary cavernomas. It provides direct access to the lesion, avoiding additional myelotomy.
