橋背部海綿状血管腫の1手術治験例—診断上MRIの有用性

Report of a Successfully Operated Carvernous Angioma in the Dorsal Part of the Puns: The usefulness of MRI in diagnosis

I．はじめに

　脳幹部海綿状血管腫は^17,18）報告例も少なく稀な疾患とされ，なかには腫瘍とみなされ放射線，化学療法を施行された症例も少なくない^1,22，），まして，その直達手術となると現在主で，わずか数例^5,10,19）を数えるのみである．しかしMRIなどの診断庁法の進歩により早期診断も可能となり，今後，手術適応となる症例も増加してくるものと思われる．

　最近われわれは他科にて橋腫瘍を疑われたが，MRI所見を中心に，年齢，臨床症状のfollow-up,CT scanにより橋背部海綿状血管腫と診断し，手術的に全摘し得た1例を経験したので，若干の文献的考察を加え報告する．

A case with cavernous angioma which was located in the dorsal of the pons was cured surgically.

A 16-year-old male was admitted with complaints of right motor and sensory disturbance. On neuro-logical examination, the patient had right hemiparesis and hemiparesthesia, and right cerebellar signs.

X-ray CT scan demonstrated a high density mass in the pons. Carotid and vertebral angiograms showed no abnormality. T1 and T2 weighted MRI clarified the pontine mass not as a tumor but a hematoma.
