Penetrating gastric ulcer presenting as a subcapsular liver abscess.

This report describes a subcapsular liver abscess secondary to a penetrating gastric ulcer. The initial read on the CT scan misinterpreted the abscess cavity as an opacified loop of bowel, although it was very conspicuous on a retrospective review. A penetrating gastric ulcer was identified with esophagogastroduodenoscopy and the subcapsular liver abscess was subsequently detected using MRI. Although the conventional treatment of this condition is surgery, successful management was accomplished with a combination of percutaneous drainage, Helicobacter pylori eradication, and acid-suppressive therapy. A review of the literature is provided, including associated cases and the diagnostic modalities used in the evaluation of this condition. This case illustrates how one can arrive at the correct diagnosis with the use of multiple complementary modalities of investigation.
