Abstract

Psoas abscess is a rare disease usually arising due to a benign underlying pathology such as tuberculous disease of spine, Crohn’s disease and diverticulitis. But it can be an uncommon presentation of intra abdominal malignancy. Spontaneous rupture of colon cancer, combined with psoas abscess formation is very rare. Most of these cases have been reported in relation to carcinoma colon. Colon is an uncommon site for neuroendocrine tumors. 70-80% of these tumors are asymptomatic and are found incidentally at the time of surgery or on colonoscopy. Through this article we report a rare case of neuroendocrine tumor (NET) of colon in an elderly man presenting as psoas abscess associated with intestinal obstruction.
