下位脳神経障害（頸静脈孔症候群）を合併した遺残性原始舌下動脈の1例

A Case of the Persistant Primitive Hypoglossal Artery with Unilateral Involvement of IX, X and XIth Cranial Nerves

　はじめに

　今回われわれは下位脳神経障害（頸静脈孔症候群）を合併した遺残性原始舌下動脈の1症例を経験した。脳血管造影の普及により，遺残性原始舌下動脈のような原始遺残動脈報告例が増加している。下位脳神経障害（頸静脈孔症候群）を合併した遺残性原始舌下動脈症例は検索した範囲で報告例はなく，本症例について若干の文献的考察を加えて報告する。

A 29-year-old woman presented with sudden hoarse-ness, swallowing disturbance and disturbance of eleva-tion of her right shoulder. Juglar foramen syndrome (Ver-net syndrome) with the persistant primitive hypoglossal artery was diagnosed. She was treated with dexametha-sone, vitamin B complexes, nicotinic acid and Lipo PGE1 and her symptoms were improved within 1 week of intravenous infusion of the drugs.

Aetiology between lower cranial nerve palsies and the persistant primitive hypoglossal artery was not proved.
