Disseminated Hydatid Disease With Extensive Abdominal and Pelvic Involvement In a Young Male: A Case Report.

Hydatid disease, a zoonotic infection caused by Echinococcus granulosus, typically involves the liver and lungs. Disseminated abdominal hydatidosis is rare and often results from cyst rupture or inadequate treatment. A 27-year-old male from rural Nepal presented with abdominal pain, jaundice, and palpable masses. Imaging revealed disseminated hydatid cysts in the liver, peritoneum, and pelvis. He had received albendazole monotherapy abroad. Surgical removal of the cysts was performed, followed by albendazole therapy. This case emphasizes the need for early diagnosis, complete management including surgery and antiparasitic therapy, and awareness of dissemination risks due to incomplete treatment.
