Abstract

Tailgut cysts (TGCs) are retrorectal cystic hamartomas and are congenital anomalies that are the result of the persistence of the hindgut. They are often discovered incidentally and often develop symptoms due to the development of infectious and malignant complications. In the case presented, the patient, who was 19 years old, had experienced isolated episodes of constipation for some months and had no abnormalities during the examination. MRI Defecography revealed a well-defined, multilocular cyst extending from the levels of S1 to S4, measuring 6 x 3 cm, having septa and no solid enhancing parts, which confirmed the presence of a tailgut cyst. The management of the disease was through complete excision. This case brings into focus the evaluation of TGCs as an important differential diagnosis consideration for children presenting with unexplained constipation.
