Abstract
- The authors report 6 cases of angiographically occult vascular malformations(AOVM's) which were diagnosed out of 18 cases of spontaneous intracerebral hemorrhage treated at Kang Nam Sacred Heart Hospital from January, 1988, to April, 1994. The age of the 18 patients ranged from 11 to 19 years. Among the 6 cases, 5 were acute in onset of symptoms, and the remainder, subacute. The location of hematoma was subcortical lobar in 4 cases, around basal ganglia in 1, and cerebellum in 1. The diagnoses of 4 cases was confirmed by operative and pathological findings and the remaining 2 cases, suspected by the radiological findings and clinical courses of the patients. Most of the cases showed the characteristic findings of AOVM either on or both the magnetic resonance imaging(MRI) and computed tomography(CT).
