Exercise‐Induced Headaches and Cerebral Venous Angiomas

Exercise‐induced headaches have been described as an isolated benign syndrome, or in association with specific intracranial pathology. There are no previous reports of their occurrence in association with cerebral venous angiomas. Three young patients with exercise‐induced headaches exhibited normal findings on neurological examinations. Computed tomography, magnetic resonance imaging, and angiography confirmed the presence of cerebral venous angiomas. Normal adrenergicinduced cerebral venous constriction occurring during exercise may cause a shift of blood into the unreactive angiomatous vessels. This, in turn, may result in local distension and headache.
