Abstract

A 18 year-old man had a progressive paraparesis over a two months period due to a thoracic intramedullary epidermoid cyst. Surgical removal of the cyst was followed by a dramatic improvement. The frequency, the clinical manifestations and the congenital or acquired nature of the dermoid and epidermoid intraspinal cysts are reviewed. The possibilities and the limits of the surgical treatment of this rare intraspinal benign tumors are discussed.
