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.

Extradural archnoid spinal cysts are rare lesions. Their localization is usually the thoracic spine. Clinically, they are a cause of spinal cord and/ or nerve roots compression. ⋯ We report the case of a 5-year-old girl with spinal cord compression symptoms who was treated by open surgery. We performed dural defect repair. The outcome was good in the immediate post operative period without complication and total recovery.

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.

One of the clinical presentations of intracranial aneurysm is unilateral oculomotor nerve palsy (ONP). The most common location is the posterior communicating artery. Surgical clipping and/or endovascular coiling of the aneurysm are the treatments. The aim of this study was to identify the factors that influence the postoperative recovery of patients who have posterior communicating aneurysm with ONP. ⋯ Early decompression of the posterior communicating aneurysm yielded satisfactory recovery and ONP can be reversible. In our patients, the first component of oculomotor function to recover was the parasympathetic fibers.

Matrix metalloproteinase 9 (MMP-9) has been shown to be a potential biomarker for outcome prediction after neuron damage. This study investigated whether MMP-9 could be used for outcome prediction after traumatic brain injury (TBI). ⋯ MMP-9 concentration in the CSF of TBI patients correlated with neurological outcome and may represent an early indicator for the prognosis of this condition.
