흉수를 압박한 고립성 연골종

Abstract

Solitary osteochondroma is a very unusual cause of spinal cord compression. The tumor is benign, and surgical removal produces an excellent clinical result. We have experienced a case of solitary osteochondroma in the posterier neural arch of the 11th thoracic vertebra which compressed spinal cord and resulted in paraparesis. Plain spine x-ray revealed calcified bony lesion with smooth border at Tll level. Myelogram showed nearly complete blockage of dye column, extradural type, at the Tll level. Total laminectomies including the pathological lesion resulted in excellent recovery.
