Retrorectal Cystic Hamartoma - A Rare Case Report

Retrorectal cystic hamartomas or tailgut cysts are rare congenital lesions which result from the non-regression of embryo remnants of the hindgut. In this case report we present a 4-year old female who was referred to our facility with a history of change in stool habit for 2 years characterized by pain during defecation and passage of flat shaped stool. Abdomino-pelvic CT scan suggested retrorectal cystic hamartoma which was successfully surgically excised through posterior sagittal approach. The final pathological diagnosis was retrorectal cystic hamartoma (tailgut cyst) with no evidence of malignancy.
