CTにて増大と消退を追跡した若年性橋出血の1例

A Case of Primary Potine Hemorrhage of The Young Adult Followed by CT Scan

I．はじめに

　原発性橋出血には，高血圧が原因と思われる比較的高齢者に発症する群と別に，いわゆるcryptic angiomaなどが原因と考えられる若年者の群のあることが知られている^{4,5,7,8,12-20）}．後者においては，発症が亜急性ないし慢性で，症状が緩徐進行性，動揺性，反復性に出現するため，神経膠腫，多発性硬化症などとの鑑別が困難な症例もある．

　今回われわれは若年性橋出血と思われた1症例を経験したので，文献的考察を加え報告する．
