Case Reports
Recurrent herpes simplex virus encephalitis after a neurological surgery: A case report.
The herpes simplex virus (HSV) is the most common cause of sporadic encephalitis worldwide. Even with proper treatment, this infection is associated with a mortality rate of 19%-30% and with potential neurologic sequelae. Recurrences of encephalitis are rare and limited to a few cases in the literature. Although the mechanism of reactivation has not yet been clarified, in our patient, the surgery might have acted as a precipitating factor. ⋯ HSV encephalitis is a rare but serious complication that should be suspected in cases of unexplained postoperative fever with altered consciousness, especially in patients with histories of encephalitic states.

Case Reports Observational Study
Clinically diagnosed postoperative venous thromboembolism in a neurosurgery practice in Nigeria.
Postoperative venous thromboembolism (VTE) is a major surgical complication, fraught with high case fatality rate, to which neurosurgical patients are particularly prone. There is dearth of data on this problem in the neurosurgical literature from sub-Saharan Africa. ⋯ Postoperative venous thromboembolism has a very high case fatality rate among these neurosurgical patients. There is need for continuing surveillance of this problem, as well as a heightened vigilance to prevent and treat it in our neurosurgical patient populations.

Isolated cortical venous thrombosis is very rare and poorly understood. The clinical presentation is also not well described in the literature. We report here a case of isolated cortical venous thrombosis that mimicked cortical subarachnoid hemorrhage (SAH). ⋯ The patient had no recurrence of symptoms. If a cord sign is present on noncontrast CT images, further studies (MRI/magnetic resonance venography or TFCA) should be performed in a step-wise manner. Such considerations could prevent a fatal outcome and poor prognosis.

Olfactory schwannomas of the anterior cranial base (ACB) are rare tumors, and their association with hereditary hemorrhagic telangiectasia (HHT) has not previously been described. The majority of ACB schwannomas arise from the sinonasal tracts and may demonstrate intracranial extension. We report a case of an olfactory schwannoma-dense adherence to the basal frontal lobe. Complete tumor resection was performed through a unilateral extended endonasal endoscopic approach with preservation of the contralateral olfactory bulb. Anterior cranial base repair was achieved with the use of a mucoperichondrial vascularized pedicled nasoseptal flap. ⋯ We report a rare case of HTT and olfactory schwannoma completely resected with a unilateral extended endoscopic endonasal approach. Reconstruction was performed with the use of nasoseptal flap. This is the first reported single-stage fully endoscopic endonasal unilateral approach for resection of an olfactory schwannoma with preservation of the contralateral olfactory cleft. The patient's sense of smell and taste was maintained after surgery.

Comparative Study
Cost analysis of spinal versus general anesthesia for lumbar discectomy and laminectomy spine surgery.
Lumbar spine surgery can be performed using various anesthetic modalities, most notably general or spinal anesthesia. Because data comparing the cost of these anesthetic modalities in spine surgery are scarce, this study asks whether spinal anesthesia is less costly than general anesthesia. ⋯ When comparing the benefits of spinal and general anesthesia, spinal anesthesia is less costly when used in patients undergoing lumbar diskectomy and laminectomy spine surgery.
