Abstract

Dermoid and epidermoid tumors arise from the invagination of epidermal elements into the neural tube during the embryonic period. However, many studies have reported that dermoid and epidermoid tumors occur 5 to 10 years after the first operation on myelomeningocele patients. A seven-year-old male with myelomeningocele which had been repaired in his neonatal period, presented leg pain and deterioration of gait disturbance and urinary incontinence. Neuroradiological examinations revealed a spinal dermoid cyst at the repaired myelomeningocele and tethered spinal cord. We removed the tumor and untethered the tethered spinal cord. Postoperatively, the patient's leg pain, gait disturbance and urinary incontinence improved immediately. Inappropriate surgical treatment of spina bifida may cause a second lesion, which leads to tethered-cord syndrome. We suggest that proper surgical treatment, early checkup and neuroradiological evaluations are very important for spina bifida patients who show signs of neurological deterioration. For the best treatment, neurological, urological and orthopedical follow-up study after the first repair operation is necessary.
