内頸動脈閉塞をきたしたNeurofibromatosisの1例

Neurofibromatosis with Occlusion of Internal Carotid Artery:Case report

I．はじめに

　neurofibromatosis（NF）は，皮膚の母斑と腫瘍，中枢神経系病変，骨の線維嚢胞性病変に代表される中胚葉および神経外胚葉系の異常である．そのなかの中枢神経系病変としては，腫瘍，過誤腫，奇形などが含まれるが，この他に稀な合併症として脳血管病変が報告されている．最近われわれはNFに内頸動脈閉塞を合併した症例を経験したので，若干の考察を加え報告する．

Vascular lesions of the central nervous system in neurofibromatosis (NF) are uncommon. Cerebral arterial occlusive diseases in NF have been documented in only 29 patients. This paper reports a case of a 16-year-old male having occlusion of the right internal carotid artery with NF. He was admitted with an episode of clonic convulsion and left hemi-paresis at the age of five years. On admission, he bad multiple café-au-lait spots, depigmentation and fibroma molle throughout his body.
