Hepatic abscess due to gastric perforation by ingested fish bone demonstrated by computed tomography.

Perforation of the gastrointestinal tract by ingested foreign bodies is rare. Preoperative diagnosis of complications due to foreign bodies in the gastrointestinal tract can rarely be achieved because the conventional radiographic appearance is nonspecific. This report describes a 69-year-old woman who presented with vague clinical manifestations, intermittent abdominal pain, and low-grade fever. Hepatic abscess, secondary to a foreign body penetrating the gastric wall, was diagnosed preoperatively using computed tomography findings. On exploration, the foreign body turned out to be a fish bone. The abscess was confirmed and drained during surgery and a partial gastrectomy was performed. This case illustrates the value of CT in the evaluation of this condition.
