Ruptured distal anterior cerebral artery aneurysm presenting with acute subdural hematoma without subarachnoid hemorrhage.

We report a case of distal anterior cerebral artery (DACA) aneurysm presenting with subdural hematoma (SDH) without subarachnoid hemorrhage (SAH). A patient in his fifties presented with headache. Fluid-attenuated inversion recovery magnetic resonance imaging revealed SDH in the interhemispheric fissure and left frontotemporal region.

Trigeminal Neuralgia due to Venous Compression Successfully Transposed by Suprameatal Tubercle Drilling.

A patient with trigeminal neuralgia due to venous compression was successfully treated by transposition achieved by drilling the suprameatal tubercle. A 53-year-old woman presented with classical trigeminal neuralgia affecting the maxillary division of the right trigeminal nerve. MRI and CT revealed a bony prominence, called the suprameatal tubercle, above the opening of the internal acoustic meatus.

Wrapping method for better fat handling in endoscopic trans-sphenoidal surgery.

Background: Fat is commonly used for preventing cerebrospinal fluid (CSF) leakage during endoscopic transsphenoidal surgery (ETSS). However, fat is soft, slippery, and sometimes not easy to handle. The present study aimed to examine the efficacy of our Surgicel wrapping method, which allows for better fat handling, in preventing the occurrence of CSF leakage among patients undergoing ETSS.

RNF213-Related Vasculopathy: Various Systemic Vascular Diseases Involving RNF213 Gene Mutations: Review.

Moyamoya disease (MMD) is a cerebrovascular disorder that is predominantly observed in women of East Asian descent, and is characterized by progressive stenosis of the internal carotid artery, beginning in early childhood, and a distinctive network of collateral vessels known as "moyamoya vessels" in the basal ganglia. Additionally, a prevalent genetic variant found in most MMD cases is the p.R4810K polymorphism of RNF213 on chromosome 17q25.
