STUDY DESIGN: A case report and a review of literature. OBJECTIVES: To describe a rare case of adult onset tethered cord syndrome associated with intradural dermoid cyst. SETTING: General Orthopedics, Japan. METHODS: A 50-year-old woman was referred to us because of right leg pain and pollakiuria. Neurological examinations and radiological assessments including myelography, computerized tomography scan and Magnetic resonance image were carried out. We diagnosed it as the adult onset tethered cord syndrome associated with an intradural cystic lesion. RESULTS: The cystic lesion was totally removed following laminectomy from L5 through S4. Histologically, the tumor was diagnosed as a dermoid cyst. CONCLUSIONS: Intradural dermoid could produce adult onset tethered cord syndrome, but it was not reported in the English literatures to our knowledge.
