11C-Methionine PET/CT in Cryptococcus Meningoencephalitis.

A 70-year-old man experienced an epileptic seizure. Subsequent MRI performed on close examination revealed high signal in the left occipital cortex on fluid-attenuated inversion recovery. Gadolinium contrast indicated enhancement along the cortex.

Effectiveness of hinge craniotomy as an alternative to decompressive craniectomy for acute subdural hematoma.

Background: Acute subdural hematoma (ASDH) is a life-threatening condition, and hematoma removal is necessary as a lifesaving procedure when the intracranial pressure is highly elevated. However, whether decompressive craniectomy (DC) or conventional craniotomy (CC) is adequate remains unclear. Hinge craniotomy (HC) is a technique that provides expansion potential for decompression while retaining the bone flap.

Coexistence of anterior choroidal artery and posterior cerebral artery retia mirabilia presenting with subarachnoid hemorrhage: illustrative case.

Background: A rete mirabile is a rare vascular anomaly, with posterior cerebral artery (PCA) involvement being especially rare. Its pathogenesis has been speculated as a remnant of "distal annexation" between the primitive anterior choroidal artery (AchA) and the PCA at this site, but the exact mechanisms remain unclear.

Observations: A 29-year-old man presented with subarachnoid hemorrhage.

Case of Cerebrospinal Fluid Leakage Nine Years after Pituitary Gamma Knife Surgery for Poststroke Thalamic Pain Syndrome.

Pituitary gamma knife surgery (GKS) is a treatment option for poststroke thalamic pain syndrome. Complications such as hypopituitarism, transient enuresis, and transient hyponatremia have been reported. However, cerebrospinal fluid (CSF) leakage has not yet been reported as a complication of pituitary GKS for poststroke thalamic pain syndrome.

Transarterial Sinus Coiling for Dural Arteriovenous Fistula: Two Case Reports.

Objective: We report two cases of dural arteriovenous fistula (DAVF) treated by coil embolization of the affected sinus and fistula via a feeding artery instead of transvenous embolization (TVE) due to the difficulty of the transvenous approach.

Case Presentation: An 82-year-old man was diagnosed with transverse sinus (TS) DAVF. A microcatheter was inserted into the isolated TS through the fistula via the middle meningeal artery (MMA), which was the feeding artery of the DAVF.
