title: [A case of venous angioma complicated by unruptured aneurysm with TIA as the initial manifestation].
abstract: Venous angioma is a relatively rare vascular malformation of the brain. It is usually asymptomatic and may be an incidental finding at autopsy or on cerebral angiography. We report a very rare case in which TIA-like attack occurred as the initial manifestation. A 59-year-old woman was hospitalized because of a TIA-like attack about 5 months after left putaminal bleeding. Detailed examination allowed us to make a diagnosis of subcortical venous angioma of the left parietal lobe and multiple cerebral aneurysms. The cerebral aneurysms were treated surgically. Since the angioma was localized in an eloquent area, radiotherapy was chosen first. Angioma giving rise to TIAs is very rare. The ischemia may have been caused by transient venous thrombosis or a steal phenomenon due to a decrease in blood circulation in the left cerebrum caused by the putaminal bleeding.
