Abstract
- Authors report 17 cases of angiographically occult vascular malformation of the brain experienced from July 1978 to February 1989. In 11 cases the diagnosis was confirmed by the operative and pathological findings and in the other 6 cases the clinical course and the radiological findings suggested the diagnosis. All the cases had the evidences of hemorrhage. Five of those had episodes of repeated hemorrhage. The characteristic findings of magnetic resonance imaging improved the sensitivity and specificity of diagnosis. Case summary and illustrative cases were presented with the review of literature.
