The author discusses the problem of surgical treatment of intracranial angiomas situated in basal ganglia and diencephalon. Vascular malformations in this area were found in 7.5% of cases in a group of 80 patients with intracranial angiomas. In all 6 cases the onset of the disease was sudden with meningocerebral haemorrhage, prolonged coma and hemiplegia. The malformations had usually the features of arteriovenous angioma. The afferent vessels come usually from the medial short and long vessels branching off from the anterior and middle cerebral arteries, the choroid arteries and the posterior communicating artery. The author isolated two types of malformations differing in their situation, shape and range of vascularization. In the "subventricular" type situated within the nucleus caudatus and lenticularis, internal capsule and thalamus the malformation can be exposed well from the approach through the lateral ventricle. The angiomas situated nearer to the base of hemisphere (the parabasal type), in the diencephalon, in the area of the olfactory triangle, substantia perforata anterior and even crus cerebri can be exposed best using the subfrontal approach. The author believes that in many cases of these malformations regarded usually as inoperable, radical operation can be done with selective removal of angioma by means of microsurgery. This procedure was applied in 2 cases (Fig. 2 and 3).
