Peritoneal and hepatic hydatid cysts


Extensive hydatid disease of the abdomen.

When humans are infected through contact with an infected animal or ingestion of contaminated vegetables or water, the oncosphere/embryo passes through the intestinal wall and into the portal circulation, most commonly resulting in hepatic hydatid disease. 

This patient likely started with hepatic disease which perforated and seeded into the peritoneum, evidenced by hepatic cyst rupture.
