A Case of Intradural Dermoid Cyst in the Cervical Region Associated with Congenital Dermal Sinus: Case Report

ABSTRACT

We report a rare case of a 10-month-old male with a cervical intradural dermoid cyst associated with a congenital dermal sinus. He was presented motor weakness of right upper extremity 1 month before admission. The cervical spinal MRI demonstrated an intradural extramedullary mass from third cervical vertebra to fourth cervical vertebra, which was connected with a skin through a sinus tract. With extensive laminectomy, the mass and the sinus tract were completely removed and the mass was histopathologically diagnosed as a dermoid cyst. six months after surgery, the neurological status return to normal and MR study showed no evidence of recurrence or any deformity. In case of the intradural dermoid cyst associated with a congenital dermal sinus, early diagnosis and total excision of the cyst, including the entire tract may provide an excellent outcome.
