Abstract
Clinical, neuroradiological and surgical findings were analysed in nine patients with venous cerebral malformations. Special emphasis has been placed on MR findings. Venous angiomas are characterised in MR tomography as low-signal areas whereas cavernous angiomas are characterised by a high incidence of signals due to the blood coagulates. In this manner MR tomography confirmed pathologico-anatomical findings to the effect that malformations are often made up of a venous and a cavernous component. Today it is also occasionally possible to clarify the aetiology of so-called "cryptogenic" epilepsies. Modern microsurgery enables the removal of a venous vascular malformation even in the parietal area without the risk of impairment or loss of nerve function.
