Intradural intramedullary teratoma presenting in the lumbar spine: report of a rare case.
Intradural teratomas are an exceedingly unusual phenomenon. They are tumors with the cellular constituent source of all the 3 germ cell layers. ⋯ Teratomas should be taken into consideration in the differential diagnosis of intramedullary lesions, even after the imaging reveals tissue homogeneity.

Postcraniotomy meningitis is a severe complication in neurosurgery, and can result in high morbidity and mortality. Closed continuous lumbar drainage (CCLD) as an adjuvant method for treating postcraniotomy meningitis in adults is rarely assessed. This study aimed to evaluate the efficacy of CCLD in the treatment of postcraniotomy meningitis. ⋯ Intravenous antibiotic and steroid therapies, assisted by CCLD, can lead to lower mortality and improved Glasgow Outcome Scale score in patients with meningitis after craniotomy. Laboratory results negative for cerebrospinal fluid leak and meningitis-related symptom relief occurred faster in the experimental group. Intravenous antibiotic and steroid therapies combined with CCLD appear to be an effective and safe treatment for postcraniotomy meningitis.

A thorough understanding of the orbit, structures within it, and complex spatial relationships among these structures bears relevance in a variety of neurosurgical cases. We describe the 3-dimensional surgical anatomy of the orbit and fragile and complex network of neurovascular architectures, flanked by a series of muscular and glandular structures, found within the orbital dura.

Although hyperglycemia is a serious complication of subarachnoid hemorrhage, its pathophysiologic mechanism based on neural circuitry has not been known. ⋯ There is an important linear relationship among the blood glucose levels, DND of the IC, and nodose ganglia and degenerated surface areas of IL following experimentally induced sylvian SAH.
