Abstract

The clinical significance of venous angiomas is controversial. Owing to the increased resolution of modern CT scannes and the advent of magnetic resonance imaging(MRI) as well as an increased awareness of these lesions, venous angiomas has been recognized more frequently in routine neuroradiographic examinations. In a retrospective study of 1998 brain MR imaging performed at our institute between April, 1990 and April, 1992, 18 cases of venous angioma were diagnosed. Among them, 13 cases(72.2%) occur supratentorially and 5 cases(27.8%) occur in cerebellum. Their symptoms were headache(7 cases), hemorrhage(4 cases) seizure(3 cases), focal neurological sign(1 case) and no associated symptoms(3 cases). All cases have been managed conservatibely except one case(with massive cerebellar hemorrhage). During follow up period, no significant complications was happened in all cases. Long-term follow up is necessary to develop meaningful recommendations regarding the management of venous angiomas.
