Cerebral venous angioma of the pons: report of a case with pontine hemorrhage.

Cerebral venous angioma in the pons associated with pontine hemorrhage in a 39-year-old normotensive woman was identified with computed tomography and angiography. Venous angioma in the brain stem is usually silent and rarely found by chance at autopsy. Only a few cases have been clinically reported. Our report indicates that in unusual cases of intracerebral hemorrhage, vascular malformations should be suspected and scrutinized with radiologic examination including angiography.
