The association between vasculopathy and radiation is well recognized. Generalized arterial disruption and subsequent stenosis and occlusion is most often described. Additional vascular phenomenon, such as pseudoaneurysm formation, aneurysmal dilatation and aneurysmal rupture, are less common. We document a case of a cerebral aneurysm formation and rupture in the field radiated for cerebral neoplasm.

Two cases of neurofibromatosis and intracranial arterial occlusive disease are reported. The radiographic and clinical features of these and twelve previously reported cases are reivewed.

A 32-year-old female developed a bruit, determined to arise from a rare direct arteriovenous (AV) fistula from the ascending pharyngeal artery to the internal jugular vein. The fistula was treated by transarterial silicone balloon occlusion, with occlusion of fistulous flow, ablation of symptoms, and excellent long-term result.
