TAIL GUT CYST- A RARE FINDING- CASE REPORT AND REVIEW OF LITERATURE

Abstract

Introduction: Tailgut cysts are rare congenital entity that arises from the embryological hindgut and usually located in presacral space. Here we report a case of tail gut cyst which is an infrequent condition. Case report: Here, we report a nineteen year old male with lower abdominal pain. The relevant investigations were performed. The CT abdomen revealed a well-dened cystic lesion in the pelvis in lower presacral region and posterior to rectum with small calcied foci suggestive of tail gut cyst with scalloping of sacrum. MRI pelvis suggested large well dened unilocular cystic lesion in the retro-rectal and pre-sacral region extending from S2 to mid coccygeal level showing thin imperceptible walls few tiny projections and small rounded non enhancing nodule along its posterior wall with thin focal calcication seen in its wall with no evidence of malignancy and no signs of osseous destruction. The patient was explored and intraoperatively ndings revealed a cyst of size 8 cm * 5 cm behind the rectum and in front of sacrum which was densely adhered to the posterior wall of rectum but free from sacrum. The mass was resected as a whole and sent for histopathological exam which was suggestive of tailgut cyst. Tailgut cysts is infrequent condition which manifests as chronic lower abdominal pai Conclusion: n. It is crucial that such entity be diagnosed and surgically excised early in its presentation. It is important to rule out malignancy in the post operative biopsy
