Review Case Reports
Bilateral Ossified Chronic Subdural Hematoma Presenting As Diabetes Insipidus- A Case Report and Literature Review.
Calcified chronic subdural hematomas are an occurrence rarely seen in neurosurgical clinical practice. And when they occur bilaterally, the radiologic image they present is fascinating, as is the clinical presentation, but their management may be challenging. ⋯ Due to the rarity of this pathology, the management protocol is not well defined, though there have been quite a few papers on this condition. This review article gathers information published over the years on this rare entity to suggest a treatment protocol.

Multicenter Study
Predictors of shunt insertion in aneurysmal subarachnoid hemorrhage.
Hydrocephalus is a common complication of aneurysmal subarachnoid hemorrhage (aSAH), requiring permanent cerebrospinal fluid (CSF) diversion in up to two thirds of patients. Factors that predict permanent CSF diversion are not well established. ⋯ Sympathomimetic illicit drug use, EVD insertion, and hyponatremia are the strongest predictors of shunt insertion in patients with aSAH. Moreover, a scoring system based on EVD insertion, Hunt and Hess grade, and modified Fisher computed tomography grade can reliably predict the need for shunt placement in patients with aSAH.

Ruptured middle cerebral artery (MCA) aneurysms usually lead to subarachnoid hemorrhage (SAH), and several cases have shown concomitant intrasylvian or intracerebral hematomas. The objective of this study was to compare the clinical and radiographic characteristics with their different outcomes. ⋯ In our series, the prognosis of patients with ICH was worse than that of patients with ISH. Early discrimination of these 2 types of hematoma helps to predict future outcome; an angle (between the pointing direction of aneurysm and the MCA trunk) between 109.0°and 216.0° is associated with ISH, whereas aneurysm with an angle beyond this range suggests ICH.

Pyogenic cerebral ventriculitis is a debilitating form of intracranial infection with an unfavorable outcome as a result of lack of experience in surgical management. ⋯ The results suggest a relatively favorable outcome for management of pyogenic cerebral ventriculitis by NES. The techniques and strategies are practical and should be applied more extensively.

Sinus pericranii is a rare vascular anomaly characterized by abnormal connections between the extra- and intracranial venous systems. Although the etiology still remains unclear, sinus pericranii is usually congenital in nature, or less likely may be secondary to spontaneous or traumatic causes. ⋯ This case highlights the effect of the reversal of normal venous outflow secondary to meningiomatous occlusion of intracranial dural sinuses. Sinus pericranii may, on rare occasions, represent the sole means for intracranial venous drainage in cases of intracranial venous thrombosis or incomplete development of the cerebral venous system. Therefore, this case also highlights the importance of pretreatment evaluation of the venous drainage system in patients with sinus pericranii and those with meningiomas.
