Cystic Echinococcosis: A Case of Extrahepatic Intra-Abdomina
Hydatid disease, or echinococcal disease, is a parasitic infestation caused by the larval stage of the Echinococcus tapeworm and it primarily affects the liver and lung but involvement of other organs is also possible secondary to peritoneal seeding or hematogeneous dissemination. We describe a rare case of extensive abdominal disease, with lesions affecting the liver, peritoneum, and lesser omentum, requiring aggressive surgical intervention. Complementary diagnostic exams were crucial to reach the diagnosis and evaluate the extension of the disease.

Case Report
We report a case of a 49-year-old Caucasian man who presents to our attention with a history of long term fatigue, increased abdominal girth, and right upper quadrant pain. The past medical history is unremarkable, with mild mental impairment secondary to neonatal meningitis and arterial hypertension; he has no past surgical history, has always lived in an apartment in a semirural region in Portugal, has never traveled outside his country, and denies contact with animals except for dogs during the childhood. Familiar history is irrelevant and no other family members had the same complaints.
