A rare malformation of the alimentary tract, tailgut cyst : a case report

Tailgut cyst (cystic hamartoma) is a rare congenital pathology that arises -from post-natal primitive gut remnants in the retrorectal-presacral space. Because of the rarity of the lesion and the variability of the anatomical position, its diagnosis and surgical treatment are often difficult. Complete surgical excision of the multilocular and multicystic process prevents recurrent draining sinuses and eliminates the possibility of malignant change. We describe a case in which a tailgut cyst localized in the retrorectal and presacral space was characterized by abscess, repeated urinary tract infection, and rectal pain.
