Hydatid thrombosis of the portal vein: a rare case report

Hydatidosis, caused by <i>Echinococcus granulosus</i>, is a widespread parasitic disease, especially in livestock areas. In Morocco, it is hyperendemic and poses a major health concern. The liver and lungs are the most affected organs, but portal vein involvement is extremely rare, with only eight reported cases. We present a 56-year-old man with a recurrent hepatic hydatid cyst, three years after a left hepatectomy. Imaging revealed hydatid thrombosis of the portal vein, a rare complication requiring distinct management from typical venous thrombosis.
