The Association of Venous and Cavernous Angioma - Case Report and Review of Literature
Isolated cavernous and venous angiomas are common vascular cerebral malformations but their association is less frequent. Presence of venous angioma enhances the risk of bleeding from cavernous angioma. Also, this association is important for surgical planning. While early extirpation of cavernous angioma is recommended, the associated venous angioma has to be preserved due to the possible venous infarction. We report a case of venous angioma associated with cavernous angioma revealed by magnetic resonance imaging after the administration of contrast material, which was not visualised on unenhanced MRI images. The importance of contrast administration in the diagnosis of venous angioma in a close vicinity of cavernous is emphasised in this report.
