Epidermoid cysts associated with thoracic meningocele

Intraspinal tumours of cutaneous origin associated with various spinal dysraphisms have been well documented in the literature. However, the metachronous development of intra- and extra-medullary tumours in conjunction with dorsal meningocele is rare. The authors report a patient with a thoracic dorsal meningocele and congenital intradural extramedullary epidermoid tumour. The patient developed an intramedullary epidermoid growth 12 years later. Subtotal resection of the tumour predisposed to a later recurrence.
