Small bowel perforation - ingested bone

Case contributed by Michael P Hartung
Diagnosis almost certain

Presentation

Progressively worsening abdominal pain over past few weeks.

Patient Data

Age: 80 years
Gender: Male

3 cm in length linear, dense foreign body within the loop of small bowel in the right mid abdomen, nearly traversing the wall. Adjacent to this are a few locules of extraluminal air with small amount of fluid.

Prior right hemicolectomy. No other acute findings.

Case Discussion

This case provides a great example of small bowel perforation due to foreign body. The appearance of the foreign body is characteristic of perforation by a thin bone fragment (most commonly a fish or chicken bone). Curiously, no foreign body was identified at the time of gross pathology, however, the CT findings of foreign body perforation are very convincing.
