Craniotomy for hematoma evacuation and aneurysm clipping is the treatment modality of choice for ruptured middle cerebral artery (MCA) aneurysms with intracranial hematomas. Recent literature suggests that endovascular coil embolization followed by hematoma evacuation can be an acceptable alternative. ⋯ MCA aneurysm rupture with concomitant large intraparenchymal or sylvian fissure hematoma formation carries a grave prognosis. Simultaneous hematoma evacuation and aneurysm clipping with or without craniectomy can be an effective treatment modality.

Low-grade gangliogliomas/gangliocytomas (GGs) are rare tumors of the central nervous system that occur mostly in young people. Because of their rarity, large-scale, population-based studies focusing on epidemiology and outcomes are lacking. ⋯ This study shows that low-grade GGs occur in older children with a male preference. Gross total resection is achieved in the majority of cases, and radiation is rarely used. Although the majority of patients have an excellent prognosis, infants and patients with brainstem tumors have worse survival rates.

During transsphenoidal surgery for pituitary adenomas with large suprasellar extension, cerebrospinal fluid (CSF) leakage commonly develops from a defect at the arachnoid recess between the resected dura margin and the anterior edge of a normal pituitary gland (type 1 CSF leakage). ⋯ Our 2 different repair techniques for arachnoid recess tears are very reliable methods for managing this type of CSF leakage. The direct suture technique may be more appropriate for type 1 CSF leakage with a wider gap and more prominent CSF leakage.

Although numerous studies have focused on the efficacy of deep brain stimulation (DBS) for movement disorders, less is known about surgical adverse events, especially over longer time intervals. ⋯ These data provide low incidences for adverse events in a large series of DBS surgeries for movement disorders at up to 10 years follow-up. Accurate estimates of adverse events will better inform patients and caregivers about the potential risks and benefits of surgery and provide normative data for process improvement.
