Skull Base Osseous Arterio-venous fistula - a rare clinical entity : Case report and Literature Review.
To describe a rare clinical entity of intraosseous skull base arteriovenous fistula managed with transvenous fistula embolization. ⋯ Skull base osseous fistulae are uncommon clinical entities and fistulae centered within the sphenoid bone are very rare. The aim of this report was to highlight management issues associated with such a case and review the available literature on the subject.

Preoperative diffusion tensor tractography (DTT) has recently been used to aid in the mapping of functional pathways to limit damage associated with resection of low-grade gliomas (LGGs). ⋯ The NF index may be a useful biomarker for predicting clinical outcomes in patients with LGGs. Furthermore, the NF index may provide a preoperative estimate of the patient's potential for recovery from possible postsurgical neurologic deficits.

The oncogenesis and biologic behaviors of benign glandular schwannoma have not been clinically unveiled because of its rarity and variability. ⋯ Therefore, the morphologic and immunohistochemical findings support the diagnosis of benign glandular schwannoma.

Review Case Reports
Value of targeted epidural blood patch and management of subdural hematoma in spontaneous intracranial hypotension.
Spontaneous intracranial hypotension (SIH) is a more common than previously noted condition (1-2.5 per 50,000 persons) typically caused by cerebrospinal fluid (CSF) leakage. Initial treatment involves conservative therapies, but the mainstay of treatment for patients who fail conservative management is the epidural blood patch (EBP). Subdural hematoma (SDH) is a common complication occurring with SIH, but its management remains controversial. ⋯ Although blind lumbar EBP is often successful, targeted EBP has a lower rate of patients requiring a second EBP or other further treatment. On the other hand, targeted EBP has a larger risk profile. Depending on the clinic situation, treatment of the SDH via surgical evacuation may be necessary.

Review
Intraventricular Meningiomas: A Series Of 42 Patients at a Single Institution and Literature Review.
Primary intraventricular meningiomas (IVMs) make up 0.5%-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. ⋯ IVMs usually reach a large size before being diagnosed. Surgical treatment is the most suitable option and total removal should represent the main goal of the procedure. The posterior parietal transulcal approach and the temporoparietal approach are the most common surgical routes used in our series.
