The results of operating upon cerebral aneurysms and angiomas in children and adolescents. II. Cerebral angiomas.

Symptomatic angiomas of the brain, brain stem or cerebellum are uncommon in all age groups. They usually present by subarachnoid and intraparenchymatous hemorrhage, but they may act as expanding mass lesions, as causes of ingavescent neurological deficit (?'steal phenomenon'), as epilepticogenic foci, or as a source of relentless headache. We have operated upon 20 patients, 18 years of age of less, with symptomatic angiomas. There has been no surgical mortality, and no patient has been made worse by operation.
