Thoracic intramedullary spinal epidermoid tumor: A rare entity

Abstract

Epidermoid cyst in the spinal cord is a rare condition. It constitutes of only 0.6-1.1% of all spinal tumors. We are reporting a case of a 22-year-old female who presented with complaints of tingling and numbness in both lower limbs since past 3 years and weakness in both lower limbs since past 1 year, which gradually progressed. Since last 3 months she was unable to walk and get up from their squatting position. Magnetic resonance imaging of spine revealed a mid-thoracic intramedullary mass with obliteration of anterior and posterior subarachnoid space, which was confirmed as an intramedullary epidermoid cyst at surgery. Total excision of intramedullary epidermoid tumor was performed. Histopathological examination of resected specimen confirmed the diagnosis of epidermoid cyst. The patient recovered progressively after initial deterioration in neurological status.
