Tailgut Cyst Causing Chronic Colonic Obstruction
Tailgut cysts are rare tumors of the presacral space, the majority of which are asymptomatic when diagnosed. Two males, 38-year-old and 47-year-old, presented with a few years history of progressive constipation and LLQ abdominal pain. In both cases, imaging revealed a large pre sacral cyst, chronically obstructing the rectum, with massive proximal dilatation. Exploration via abdominal approach revealed a large tailgut cyst, with an extremely dilated sigmoid colon. Complete resection of the cyst required segmental colon resection and staged surgery in one case. These cases demonstrate that tailgut cysts, if left untreated, may produce a significant mass effect, and require complex surgery, thus supporting the approach of excision when diagnosed, even if asymptomatic.
