Abstract
BACKGROUND Spontaneous cerebrospinal fluid (CSF) leaks occur when there is a tear in the dura mater. Spontaneous CSF leaks are rare, and often associated with conditions like intracranial hypertension, connective tissue disorders, or congenital defects in the dura mater. CASE REPORT The patient was a 66-year-old woman who presented to the Emergency Department with clear, positional nasal discharge from her left nostril for 1 week. She had a history of chronic headaches, which seemed to have been relieved around the time of onset of her rhinorrhea. Diagnostic imaging, including computed tomography and magnetic resonance imaging scans, confirmed the presence of a CSF leak and a left temporal meningoencephalocele. The patient subsequently underwent surgical repair of the leak and ventriculoperitoneal shunt placement, and was discharged home in stable condition. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early detection of CSF leaks require a thorough history and physical examination, and is crucial in preventing potentially life-threatening complications such as meningitis and intracranial abscesses.

Abstract
Spontaneous intracranial hypotension is a condition resulting from cerebrospinal fluid leaks at the spinal level that disrupt the regulation of intracranial pressure. This disorder is an uncommon cause of debilitating headaches but can have variable clinical manifestations, which contributes to delayed diagnosis and potentially severe consequences. The standard treatment consists of conservative measures such as bed rest, hydration, and a pharmacological approach with paracetamol, caffeine, ergotamine, and dexamethasone. When conservative measures fail, an epidural blood patch is the gold standard treatment, where a small amount of blood is injected into the epidural space to form a clot to seal any existing leak. Recent studies showed a success rate of 64% without the need for further intervention. The authors report a case of a 55-year-old woman with a three-month history of daily severe headaches. Imaging exams showed subdural collections, suggesting the hypothesis of cerebrospinal fluid hypotension. After the failure of conservative measures, an epidural blood patch was performed with progressive clinical improvement. This case demonstrates the potential effectiveness of an epidural blood patch in the management of spontaneous intracranial hypotension and its complications, offering an encouraging option for those unresponsive to conservative measures. It also highlights the importance of a multidisciplinary approach involving neurologists and anesthesiologists.

Abstract
Spontaneous intracranial hypotension (SIH) may lead to cerebral venous thrombosis (CVT). This case report describes the diagnostic and treatment processes used for a patient with CVT caused by SIH due to spontaneous spinal cerebrospinal fluid (CSF) leakage in the high cervical region. Clinical data were collected from a 37-year-old man with an initial symptom of spontaneous posterior cervical pain. The diagnostic and treatment processes of SIH-induced CVT were described. A magnetic resonance imaging (MRI) study showed superior sagittal sinus thrombosis, and a lumbar puncture revealed a low initial CSF pressure of less than 60 mmH2O. The patient underwent anticoagulation and fluid rehydration therapies. No abnormalities were observed in the thoracic MRI scan, but a cervical MRI scan revealed a spontaneous CSF leak. An epidural blood patch with autologous blood was performed, and symptoms completely resolved 3 days after the procedure. This report proposes a diagnostic procedure for detecting rare cases of SIH-induced CVT, thereby preventing future misdiagnoses and delayed treatment. When a patient presenting with CVT in conjunction with intracranial hypotension has no history of trauma or piercing, SIH caused by spontaneous spinal CSF leakage should be considered as a potential cause of secondary low intracranial pressure. For detection of CSF leaks at rare sites, an MRI of the whole spine rather than a localized MRI of the spine needs to be performed to avoid misdiagnosis. An epidural blood patch should be performed as soon as possible as it may shorten the length of hospitalization and improve prognosis.

Abstract
OBJECTIVE Spontaneous intracranial hypotension (SIH) remains a rare and difficult clinical entity to diagnose and treat. Epidural blood patch (EBP) of the dural sac is the mainstay definitive treatment for refractory cases and has mixed efficacy. We sought to evaluate the recent efficacy and outcomes of EBP for SIH at our institution. METHODS Twenty-three patients (14 women, 9 men, mean age 49) were seen and treated for SIH between Summer 2009 and Spring 2018 at the same institution. All patients underwent brain MRI with and without gadolinium contrast and T2-weighted spine MRI. Targeted EBP was placed one or two vertebral levels below areas of suspected leak, while the patient was positioned in the lateral decubitus position. Patients were seen in the outpatient setting within a week following initial EBP and repeat EBP was offered to patients with persistent symptoms. Patients were followed if symptoms persisted or for 6 months following clinical relief of symptoms. RESULTS 22/23 (95.7%) patients presented with complaints of orthostatic headache, and 3 (13%) patients presented with altered mental status (AMS) or focal neurologic deficit. Brain MRI demonstrated pachymeningeal enhancement in 16/23 (69.6%) patients, and 5/23 (21.7%) patients had a subdural hematoma (SDH) present. Dural leaks were successfully identified in 18/23 (78.3%) patients. 12/23 (52.2%) patients had symptomatic relief with initial EBP, and 5/23 (21.7%) patients received further EBPs for persistent disease with all achieving relief after repeat EBP. 5/12 (41.7%) of patients had recurrent symptoms after initial relief with EBP, and 4/5 (80%) were successfully treated with a second EBP. The mean initial EBP volume and number of EBPs per patient were 21.7 mL (median 20 mL, 7-40 mL) and 3.54 (median 1, 1-13) respectively. There was one complication from initial EBP (cervical dural tear requiring operative closure) treated with open surgical management successfully. In total, 18/23 (78.2%) patients are currently asymptomatic with regard to their SIH. The mean follow-up in this cohort was 2.6 years (median 1.8 years, 1.8 months-9.27 years). CONCLUSIONS EBP is a viable and effective option for the treatment of recurrent SIH caused by cerebrospinal fluid (CSF) leaks.

Abstract
Objectives Current evidence suggests a link between idiopathic intracranial hypertension (IIH) and spontaneous cerebrospinal fluid (sCSF) leak, as well as between IIH and dural venous sinus (DVS) narrowing. However, there are limited data linking DVS narrowing and sCSF leak. This study aims to determine the prevalence of DVS narrowing in patients with sCSF leak. Methods A retrospective review of all patients with sCSF leak that presented to a tertiary academic center from 2008 to 2019. Preoperative imaging was independently reviewed by two neuroradiologists to evaluate for DVS narrowing. Available literature was used to estimate the prevalence of DVS narrowing in the general population to allow for comparison. Data were analyzed using Exact binomial test. Results Analysis of 25 patients with appropriate imaging revealed the majority were women (21/25, 84%) with a mean age of 51.89 years (SD 13.96). The majority of these patients were found to have narrowing of the DVS (20/25, 80%). In patient with sCSF leaks, there was a significantly higher proportion of patients with DVS narrowing compared with published literature examining this condition in the general population (80% vs. 40%, CI 0.59-0.93, p < .001). Conclusion The prevalence of DVS narrowing in patients with sCSF leaks is substantial and likely greater than the general population. Moreover, there appears to be narrowing in most patients with sCSF leak. Preoperative radiological evaluation of the DVS using MR venography may be useful in patients with sCSF leaks as DVS stenosis may be an underdiagnosed etiology. Further study is needed to evaluate this. Level of Evidence IV.

Abstract
PURPOSE OF REVIEW Idiopathic intracranial hypertension (IIH) is a disorder of raised intracranial pressure (ICP). Although the majority of patients with IIH present classically with headache and papilledema, some patients may have unusual presentations or manifestations. Recent advancements in neuroimaging have facilitated the identification of other presentations associated with IIH. This review provides an overview of the expanding clinical spectrum of IIH. RECENT FINDINGS Presentations of IIH that are considered unusual include highly asymmetric or unilateral papilledema, IIH without papilledema, and IIH associated with cranial nerve involvement. These presentations likely reflect differences in the way cerebrospinal fluid (CSF) pressure is transmitted intracranially. Radiological signs of intracranial hypertension are increasingly recognized in patients with IIH and provide further insights into the effects of raised ICP on intracranial structures. Osseous changes in the skull base leading to formation of meningoceles and encephaloceles have been identified in patients with IIH, spontaneous skull base CSF leak, and drug-resistant temporal lobe epilepsy, suggesting a possible association. SUMMARY Clinicians should be familiar with the expanding clinical spectrum of IIH and the implications for the management of these presentations.

Abstract
STUDY OBJECTIVES To establish the prevalence of obstructive sleep apnea (OSA) in patients with spontaneous cerebrospinal fluid (sCSF) leaks and demonstrate the reliability of home sleep apnea testing (HSAT) to screen for OSA in this population. METHODS A literature review was performed to assess data on OSA prevalence in sCSF leaks. An institutional retrospective review was performed of 20 patients with sCSF leaks who met inclusion criteria. Patients without prior sleep studies were prospectively administered sleep studies, either HSAT or polysomnogram (PSG). RESULTS Twenty patients met the inclusion criteria. Two patients had prior sleep studies while 18 patients obtained prospective sleep studies following diagnosis and prior to management of sCSF leaks. Nineteen patients (95%) had evidence of mild or greater OSA. CONCLUSIONS This study re-demonstrates the high prevalence of OSA in patients with sCSF leaks, consistent with current literature, and investigates the reliability of HSAT for diagnosis of OSA in this population.

Abstract
Background Spontaneous cerebrospinal fluid leak (sCSFL) has been historically related to obesity and elevated intracranial pressure (ICP), with a lower rate of success of endoscopic repair reported in the literature. Moreover, defects related to this condition have been largely repaired with multilayer reconstructions and pedicled flaps. Long-term postoperative results have not been appropriately discussed yet. Objective The aim of this study is to investigate the outcome of a cohort of patients treated with single-layer mucoperichondrial graft. Methods A retrospective review of clinical records of a consecutive series of patients who underwent endonasal endoscopic surgery for sCSFL was carried out at a tertiary care referral center for skull base pathologies. All patients underwent reconstruction with single-layer mucoperichondrial free graft. Local flap failures and postoperative outcomes, in terms of recurrence of sCSFL or brain herniation, were registered. Results Neither intraoperative nor perioperative complications were reported. Definitive closure was achieved in 27 of 29 (93%) patients after the first attempt, while in 2 cases, a revision surgery was required. In both of these, an inadequate position of the graft was detected and was repaired likewise with the same mucoperichondrial graft. None of the patients required postoperative lumbar drain placement. After a median follow-up period of 57 months, only 1 patient developed a meningocele without CSFL about 2 years after surgery at the contralateral lateral recess of the sphenoid sinus. None of the patients reported symptoms referable to elevated ICP nor underwent ventricular derivation. Conclusions Single-layered mucoperichondrial free graft was safe and effective in the majority of the examined patients. In 7% of the study population, a surgical revision was necessary due to local failure of the graft. However, during long-term follow-up, only 1 case of recurrent meningocele without CSFL was reported in a patient who presented borderline ICP.

Abstract
Objective Determine the efficacy of using a purely transmastoid approach for the repair of spontaneous cerebrospinal fluid (CSF) leaks and further elucidate the relationship of elevated body mass index (BMI) and skull base thickness in our patient population. Method We conducted a retrospective chart review of patients treated for spontaneous temporal bone CSF leaks at our tertiary care institution from the years 2006 to 2015. Cases were categorized as primary or secondary. We analyzed success rates, length of stay, use of lumbar drains, BMIs, and rates of meningitis. Skull base thickness was compared with BMI in each case. Results We identified 26 primary operations for spontaneous CSF leaks and 7 secondary operations. Twenty-three of 33 repairs were performed via the transmastoid approach alone with an 87% success rate (20/23). Of the10 repairs including a middle cranial fossa (MCF) or combined MCF-transmastoid approach, 2 failed for an 80% success rate (8/10). Five transmastoid repairs underwent placement of a lumbar drain versus all 10 repairs employing an intracranial exposure. Average length of stay for those undergoing a transmastoid approach (1.7 days) was significantly shorter than for patients undergoing a MCF repair (6.3 days). Four patients presented with meningitis. Average BMI was 35.3. No correlation was established between BMI and skull base thickness ( R2 = 0.00011). Conclusion The transmastoid approach is effective in the majority of cases and prevents the need for an intracranial operation, resulting in lower morbidity and a shorter length of stay. We believe that this is the preferred primary approach in most patients with spontaneous CSF leaks.

We present a case report of a 60-year-old woman with a spontaneous cerebrospinal fluid leak at the clivus, obesity and no history of trauma. Follow-up imaging scans confirmed enlargement of the defect within the posterior clival framework to the size of 16 × 9 × 4 mm with a suspected meningocerebral hernia. The surgeons used the “two nostrils – four hands” endoscopic operating technique. The patient reported a history of cerebrospinal fluid leaks lasting for 3 years, with increasingly shorter leak-free periods and an increasing incidence of inflammatory complications. The patient recovered without complications, and she was discharged 14 days after the surgery. Good local outcome and improved patient condition were achieved postoperatively.

Abstract
Background: Patients with chronic postural headaches may suffer from spontaneous intracranial hypotension (SIH). Trauma, degenerative disc spurring and connective tissue disorders are documented risk factors; in most cases there is no inciting event. Despite sophisticated means of evaluating the neuraxis, many cerebrospinal fluid (CSF) leaks are radiographically occult and treatment is focused on thoracic and cervical-thoracic regions. Although lumbar epidural blood patch (EBP) is the initial treatment of choice after failed conservative management, several studies document the need for treatment aimed at the specific leak area. Case Description: This report describes the case of a 42-year-old female with scleroderma and sudden onset postural headaches. Magnetic resonance imaging revealed diffuse pachymeningeal enhancement suggestive of intracranial hypotension. Computed tomographic myelography demonstrated a collection of fluid ventral to the cervical thecal sac; an exact location for CSF egress was not identified. Conservative measures followed by lumbar EBP failed to alleviate her symptoms. The patient underwent placement of a lumbar drain and dynamic radionuclide cisternography (RIC). Panoramic images of the spine were taken at the time of the pressurized saline injection. The CSF leak was clearly visualized at C1–2. Treatment was focused at this region using percutaneous injection of autologous blood and fibrin glue. Conclusion: SIH is disabling if left untreated. Spinal CSF leaks are often discrete and difficult to identify using static imaging. The use of pressurized, RIC by lumbar drain injection allows for the real-time evaluation of CSF dynamics and can more precisely identify slow flow leaks often missed with static imaging.

Abstract
OBJECTIVES This case presents a previously undescribed clinical scenario of spontaneous cerebrospinal fluid (CSF) leaks secondary to a lateral sphenoid sinus recess skull base dehiscence and contralateral Sternberg's canal. This case report aims to characterize the presentation and successful management of these lesions. METHODS The electronic medical record was used to collect information pertaining to the patient's clinical history. RESULTS The patient was a middle-aged, obese female with persistent clear rhinorrhea as her only presenting symptom. Neuroradiologic studies localized the defect to the lateral sphenoid sinus recess. CSF opening pressures were within normal limits, but radiographic findings were consistent with elevated intracranial pressure. After an endoscopic transnasal transsphenoidal approach failed to resolve the CSF leak, a transpterygoid approach facilitated CSF leak resolution. The patient then did well for the following 2 years, but later developed a CSF leak through a contralateral Sternberg's canal. An endoscopic suprapterygoid procedure and ventriculoperitoneal shunt placement led to CSF leak resolution. CONCLUSION This case demonstrates one of the only published examples of a sphenoid sinus CSF leak secondary to Sternberg's canal as it was originally described in the literature. Wide endoscopic surgical exposure and intracranial pressure management ultimately led to CSF leak resolution.

Abstract
Sternberg's canal is a congenital bony defect in the lateral wall of the sphenoid sinus. If it persists to adulthood, it may become a source of spontaneous cerebrospinal fluid leak (CSF) and meningoencephalocele. The aim of the study was to describe the authors' experience and review articles related to spontaneous sphenoid sinus CSF leaks and Sternberg's canal. We analysed patients managed surgicallly due to sphenoid sinus CSF leak and performed a PubMed database search. Two female patients with spontaneous CSF leak of sphenoid origin were found. Both patients underwent surgery with the endoscopic endonasal approach, and the defect was closed using the multi-layer technique. Twelve articles related to CSF leaks of sphenoid origin (due to Sternberg's canal) were found in the PubMed database. Lines of lesser resistance within sphenoid bone may underlie CSF leak pathology together with intracranial hypertension. The endoscopic transnasal approach to the sphenoid sinus is an excellent alternative to standard transcranial procedures.

Abstract
OBJECTIVE To determine whether the transmastoid approach to repair of spontaneous temporal bone cerebrospinal fluid (CSF) leak is safe and effective and if improvement in conductive hearing loss is an achievable goal with this approach. STUDY DESIGN Case series with chart review. SETTING Tertiary academic medical center. SUBJECTS AND METHODS Fifteen consecutive patients (16 ears) presented with spontaneous temporal bone CSF leaks over a 6-year period. Clinical data, imaging, audiometry, operative reports, and postoperative course were reviewed. RESULTS Median age was 59.5 years. Mean body mass index was 40.7 kg/m2. All presented with chronic otorrhea after tympanostomy tube placement and conductive/mixed hearing loss. The mean preoperative air-bone gap was 19 dB. A transmastoid approach alone was used in 15 cases; 1 underwent middle fossa craniotomy. Most defects were located in the tegmen mastoideum and tympani. All repairs were multilayered, typically using autologous mastoid bone, temporalis fascia, and tissue sealant. Primary repair was successful in 15 cases; 1 patient with persistent postoperative otorrhea subsequently underwent middle fossa craniotomy, but no frank leakage was found. No serious complications were encountered. Following transmastoid repair, postoperative audiograms were available for 14 patients. The mean improvement in air-bone gap was 12 dB. Closure of the air-bone gap to ≤12 dB occurred in 100% of cases. CONCLUSION The transmastoid approach to repair of spontaneous temporal bone CSF leak is highly successful. Furthermore, patients in this series had excellent hearing results with closure of their air-bone gap to ≤12 dB, which has not been previously described.
