Randomized Controlled Trial
Chronic subdural hematomas: single or double burr hole-results of a randomized study.
To analyze the analysis of recurrence rates of single versus double burr holes in patients with subacute and chronic subdural hematomas. ⋯ Most of the subdural hematomas can be dealt by single burr-hole drainage.

Schwannomas are common, truly encapsulated and benign peripheral nerve sheath tumors. Their occurrence in extracranial locations is rare. Schwannomas most commonly occur in adults between 20 and 50 years of age. ⋯ No neurological deficit was noted postoperatively. The result of the histopathological examination was reported as schwannoma. We report a case of large sciatic schwannoma with chronic sciatica.

Lymphoplasmacyte-rich meningioma (LPM) is one of the rarest variants of meningioma and those LPMs that arise in the intraventricular space are even rarer. LPMs are classified as grade I (benign) tumors with a low proliferative rate and diagnosis is made through the histological identification of high numbers of inflammatory cells (lymphocytes and plasma cells) in the resected tumor tissue. ⋯ Histological analysis revealed large numbers of inflammatory cells, confirming the diagnosis of LPM, but also indicated that the lesion was positive for the proliferation marker Ki-67. Follow-up magnetic resonance imaging 3 months after surgery revealed no residual tumor or recurrence.

Sacral fractures are generally seen together with pelvic ring fractures. They can also develop in isolated form rarely. Instability is observed in these fractures in rates reaching 30%. ⋯ Serious spinopelvic instability can be talked of in sacral fractures accompanied by pelvic fractures, particularly when the anterior and posterior integrity of the pelvic ring is interrupted together. An aggressive stabilization and fixation must be performed without delay.

The aim of this study was to better define the microsurgical anatomy of the supra/parasellar region and describe variations of the anterior clinoid process (ACP). ⋯ This study contributes to the relationship of important vascular, neural, bone and dural layers of this region and also demonstrates the variations of ACP by means of microsurgical dissections and radiological examinations.
