脊髄空洞症の4例その発生病理と治療法について—その発生病理と治療法について

Syringomyelia, Its Pathogenesis and Surgical Treatment based on 4 Cases' Experience

I．はじめに

　CT scanの普及により脊髄空洞症の診断は比較的容易となったが，その発生病理，病態については未解決の部分も多く，その治療法も確立されたものはない．著者らは，各々異なる発生機序と考えられる4例の脊髄空洞症を経験した．これらの症例を基にし，その発生病理，治療法について検討を加える．

Four cases of syringomyelia, each were considered to have different pathogenesis of syrinx and presented different clinical and rediological pictures, are reported.

Case 1 was associated with Chiari I malformation and the syrinx communicated with the fourth ventricle through the central canal, case 2 was associated with Chiari II malformation and the syrinx was not com-municated with the fourth ventricle, case 3 was thought to be traumatic and case 4 to he arachnoiditis due to unknown etiology. Metrizamide CT myelo-graphy was most valuable diagnostic technique todisclose the syringomyelic cavity and its extension.
