頸胸椎移行部脊柱管内発生骨軟骨腫による対麻痺の1例

A case report:Intraspinal canal osteochondroma at the cervicothoracic junction causing spinal cord compression

I．はじめに

　一般に骨軟骨腫は長管骨骨幹端部付近に発生することが多く，脊椎に発生することは少ない．そのため骨軟骨腫により脊髄圧迫症状を呈することは非常に稀である．今回われわれは第7頸椎椎体後縁に発生し脊髄圧迫症状を呈した骨軟骨腫の一例を経験したので若干の文献的考察を加えて報告する．

Abstract

Osteochondromas are one of the most common benign tumors. They typically develop on long, tubular bones, only rarely compressing the spinal cord.

We report the case of a 9-year-old boy who suffered paraparesis secondary to a cervical osteochondroma based at the vertebral body. The tumor was removed using laminectomy.

CT scanning, plain X-ray films, and MR imaging were used in the preoperative assessment of the lesion and the operative method.
