Tailgut cyst in a female infant with a skin dimple at the coccygeal region

A tailgut cyst is a congenital cystic lesion that is situated at the presacral and postrectal area and is considered to be a remnant of the tailgut that develops in early fetal life and usually regresses later. Approximately 20 pediatric cases of tailgut cyst have been reported. We report an infantile case of tailgut cyst that was complicated with a skin dimple at the coccygeal region. The cyst was completely resected and the pathological diagnosis was mature teratoma. We finally diagnosed it as a tailgut cyst by several clinical findings including the site of the cyst, MRI image, the fact that it was complicated with a skin dimple, and the pathological findings.
