[Neuroradiologic study using modern imaging procedures (CT:NMR) in venous, cerebral vascular malformations]

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.
