Congenital dermal sinus communicated with the spinal canal is rare and fourteen cases have been reported in Japan. We would like to report one case of this disorder. Our case is a five-year-old girl. She has a congenital dermal sinus (associated with dimple, pigmentation and hair.) in the sacral region. Roentgenogram showed spina bifida occulta in the second sacral vertebra. Myelography showed complete obstruction below the level of the third lumbar vertebra.
Laminectomy and removing of cyst were carried out. Symptomes are improving of ter surgery.
