Sigmoid carcinoma with foreign body perforation

Case contributed by Dr Wayland Wang


Acute abdominal pain after eating a roast chicken.

Patient Data

Age: 70 years
Gender: Male

Peritoneal free gas is present in keeping with perforation. The sigmoid demonstrates surrounding fat stranding. A tubular osseous density structure is present in the sigmoid colon, suspicious for ingested foreign body.

Just distal to the foreign body there is a stenosing luminal mass, with stranding in the sigmoid mesocolon and tubular soft tissue extension beyond the colonic serosa.


Sigmoid carcinoma with associated perforation, which is likely related to impaction of an ingested foreign body (fragment of animal bone).

Case Discussion

This is an unusual presentation of a sigmoid cancer, with an impacted foreign body (fragment of animal bone) resulting in perforation.
