The cases of a disease with abnormal intracranial vascular network have been reported in Japan and it is said that the disease occures quite often among Japanese people. The disease has not been determined whether this can be included in one category or a syndrome complex of polygenetical disorders. The disease can be summarized ; As clinically : 1) The disease has been found from 1 to 50-year-old but usually onsets at a very young age, mainly around 10 years. 2) Akinetic seizure, hemiparesis, convultion, loss of consciousness, and aphasia etc. are common and recur episodically. As angiographically : 1) Occlusions and narrowing of arteries are commonly found at the supraclinoid portion of internal carotid artery or the proximal portion of cerebral arteries. 2) Abnormal vascular networks are found at the basal region. 3) The above mentioned changes are mainly seen bilateraly. The malformation theory and the occlusion theory are tried in an attempt to explain the cause of the disease; the authors take the latter. At this time, authors have observed 12 cases of the disease with intracranial abnormal vascular network and would like to discuss the angiographical study of this abnormal vascular network development. The abnormal vascular network will be expressed simply A.V. N.
