Parietal mass caused by a fish bone: case report.

Abstract

The authors report a case of a patient who presented with periumbilical abdominal pain and a computed tomography (CT) scan that revealed the presence of periumbilical fat infiltration on a foreign body admitted on the Department of Digestive Cancer Surgery and Liver Transplantation, Casablanca, Morocco. An exploratory laparotomy revealed a parietal mass centered by a fish bone. Accidental ingestion of foreign bodies is common in clinical practice. However, perforation of the intestine by a foreign body is less common because the majority of foreign bodies pass without incident into the feces and only 1% of them (the sharpest and most elongated objects) will perforate the gastrointestinal tract, usually at the level of the ileum.CT, especially multidetector CT, is considered the method of choice for preoperative diagnoses of ingested foreign bodies and their complications due to its high-quality multiplanar capabilities and high resolution.Foreign body ingestion usually goes unnoticed, but the complications of this incident can be severe. This case report highlights the fact that intestinal perforation caused by an ingested foreign body is a difficult diagnosis that should always be suspected in an attack of abdominal pain. Frequently, the clinical diagnosis is difficult, and recourse to imaging is sometimes necessary. Most of the time, the treatment is only surgical.
