Aneurysm of the Artery of Wollschlaeger and Wollschlaeger.

The Artery of Wollschlaeger and Wollschlaeger (AWW) is a non-eloquent, tentorial branch of the superior cerebellar artery (SCA). Coursing posteriorly from an intradural origin, the AWW passes through the ambient cistern and supplies the medial tentorium. Due to its small diameter, the AWW is often only identified in the context of secondary dilation from pathologies such as dural arteriovenous fistulas (DAVF).

Case-Control Study of Cephalometrics in Patients with Moyamoya.

Objective: To determine whether cranial metrics consistently differed between patients with moyamoya and age-, sex-, and race-matched controls.

Methods: Patients diagnosed with moyamoya disease by cerebral angiogram were obtained from a prospectively collected database through the Department of Neurosurgery at the University of Kansas Medical Center. Control patients matched by decade of age, sex, and race were collected through a deidentified hospital database by International Classification of Diseases-9 and 10 codes for ischemic stroke to identify patients with computed tomography angiograms.

Post-myelography paraplegia in a woman with thoracic stenosis.
