Abstract

Hydatid disease in humans is a parasitic disease typically caused by the larvae of Echinococcus granulosus. Although the disease can occur in any body part, it most frequently affects the liver. Hydatid disease is usually diagnosed incidentally and presents with various types of cystic lesion in the infected anatomical locations. Among the many potential complications of hepatic hydatid cysts, including rupture, infection, biliary communication, and peritoneal seeding, spontaneous rupture of the cyst into the hollow viscera is exceptionally rare and has been reported in less than 0.5% of cases. We report the case of a patient with hepatic hydatid disease complicated by spontaneous rupture into stomach causing gastric ulcer and peritoneal seeding.

  Fig. 1 Hepatic hydatid disease causing gastric ulcer as rare complication in a 49-year-old man. A. An endoscopic image shows a deep ulcer in the lesser curvature side of the gastric upper body surrounded by edematous mucosa. B. An axial contrast-enhanced CT image reveals a round mass (arrow) with mottled air bubbles in the gastrohepatic ligament, causing gastric ulceration (arrowhead). C. A coronal contrast-enhanced CT image demonstrates that the mass (arrows) is located in the hepatic left lateral segment and gastrohepatic ligament, and shows a daughter cyst (arrowhead) and peripheral coarse calcifications. D. An axial contrast-enhanced CT image reveals another cystic mass in the pelvic cavity (arrow) in addition to the hepatic mass. E. Gross surgical specimen demonstrates a turbid fluid-filled cystic mass that contains variable-sized daughter cysts. F. A photomicrograph shows protoscolices (arrows) within necrotic debris (hematoxylin and eosin stain, × 400).
