Cervical Meningeal Chondroma: A Case Report

Abstract

Soichiro Takamiya

Spinal chondromas are rare tumors, usually classified as periosteal chondroma or enchondroma, according to their origin. We describe a rare case of cervical spine meningeal chondroma in a 79-year-old man, who presented with right-sided weakness and lower-extremity dysesthesia. Magnetic resonance imaging revealed a tumor at the C1-C2 level. We suspected it to be meningioma and performed tumor excision. However, the final pathology diagnosed it as a meningeal chondroma. After surgery, his symptoms gradually improved. This case shows that, although uncommon, spinal chondromas may arise from the meninges. A good outcome is expected after total resection of the tumor.
