[New aspects of the diagnosis and therapy of microangioma].

Microangioma means a clinical entity of different arterio-venous vascular malformations. Often so called atypical intracerebral hemorrhage or a symptomatic epilepsy are caused by these malformations. Nowerdays diagnosis is much more easier by the new imaging devices like CT and MRI. Especially MRI allows to interpretate the dignity and exact localisation of these malformations. Therefore microsurgical extirpation without postoperative morbidity becomes possible.
