Spinal cerebrospinal fluid (CSF) leaks are the cause of spontaneous intracranial hypotension (SIH). ⋯ Safe sealing (with IOM) of all CSF leaks around the 360° surface of the dura is feasible through a single posterior approach. The exact surgical trajectory is selected according to the anatomic category of the leak.

Return to the operating room (ROR) has been put forth by the National Quality Forum and the American College of Surgeons as a surgical quality indicator. However, current quality metrics fail to consider the nature and etiology of the ROR. ⋯ Unplanned RORs were relatively rare and most commonly associated with wound complication, postoperative hematoma, and CSF leak. To better reflect surgical quality, ROR metrics should indicate whether the return was planned or unrelated.

Understanding spinothalamic tract anatomy may improve lesioning and outcomes in patients undergoing percutaneous cordotomy. ⋯ In the high cervical spinal cord, spinothalamic fibers mediating sharp pain for the arms are located ventromedial to fibers for the legs, and these fibers are spatially distinct from fibers that mediate heat pain.

Persistent Metabolic Disturbance in the Perihemorrhagic Zone Despite a Normalized Cerebral Blood Flow Following Surgery for Intracerebral Hemorrhage.
We hypothesized that reduced cerebral blood flow (CBF) and/or energy metabolic disturbances exist in the tissue surrounding a surgically evacuated intracerebral hemorrhage (ICH). If present, such CBF and/or metabolic impairments may contribute to ongoing tissue injury and the modest clinical efficacy of ICH surgery. ⋯ Despite normalization of CBF following ICH evacuation, an energy metabolic disturbance suggestive of mitochondrial dysfunction persists in the perihemorrhagic zone.

This report illustrates a case of a low-grade glioma that showed significant disease progression during pregnancy, and then subsequent regression spontaneously in the postpartum period without treatment. This is a rare case of spontaneous glioma regression in the postpartum period, and may suggest underlying mechanisms of hormonal influences upon glioma progression. ⋯ A young woman with a tectal glioma developed symptomatic disease progression during pregnancy, and subsequently had regression of the lesion and symptoms in the postpartum period without treatment. This case supports watchful waiting in select cases and suggests a potential role of hormones in glioma progression.
