Congenital dermal sinus in mid-dorsal spine with large intramedullary dermoid cyst in an 18-months-old child.
Intramedullary dermoid cyst is a rare entity. It is usually associated with spinal dysraphism and dermal sinus. Our case is an 18-months-old female child who presented with history of fever and mild difficulty in moving left leg. She had a sinus in mid dorsal spine since birth with history of intermittent discharge from it. On magnetic resonance imaging of spine she was diagnosed to have large intramedullary epidermoid/dermoid cyst in the D2-7 vertebral level with a sinus tract. A dermoid cyst along with the sinus tract was excised. Post-operative follow up period was uneventful with full recovery.
