Spinal epidermoid cysts
Epidermoid cyst in the spinal cord is a rare condition, constituting only 0.6–1.1% of all spinal tumors.1 The majority of spinal epidermoid cysts are subdural and extramedullary, while intramedullary localization is very rare.
Intramedullary epidermoid cyst is common in lumbosacral and thoracic regions; two frequent localizations are T4–T6 and T11–T12, while only three cases have been reported with cervical cord involvement.
The symptoms at presentation of epidermoid cysts in the lower thoracic and upper lumbar regions are usually neurologic, such as progressive paraparesis and motor–sensory complaints; sphincter troubles may occur later.
We report a case of a 13-year-old patient with an intramedullary epidermoid cyst presenting with urological manifestations.
