척수강내에 발생한 선천성 표피양 낭종: 증례보고

Abstract

The epidermoid cyst is formed as the result of inclusion of epithelial elements at the time of closure of the neural tube. The incidence of this tumor is less than 3% of all spinal canal tumors in children, The authors have experienced a 6-year old child with intraspinal epidermoid cyst which presented with symptom of back and abdominal pain. The magnetic resonance imaging study showed intraspinal mass lesion from level of T12 to S1. The patient had no history of previous lumbar puncture. We have removed totally the pearly-like intradural mass with laminoplastic laminotomy from T12 to L5. The pathological findings were compatible with epidermoid cyst. The postoperative course was uneventful without any neurologic deficit. Characteristics of this lesion with a pertinent literature is reviewed.
