Extrahepatic intraabdominal hydatid cyst: a case report

Hydatid disease, also known as echinococcosis, is a zoonotic parasitic infection caused by the larvae of the Echinococcus tapeworm. It is endemic in various regions worldwide, particularly in rural areas of countries in southern South America, Central Asia, China, parts of Africa, the Mediterranean, and parts of the Middle East. The disease primarily affects the liver (60-70% of cases) and the lungs (10-25% of cases), but it can involve any organ, including the brain, bones, and rarely the pelvic region, as seen in our case report. Hydatid disease typically follows an asymptomatic course in the early stages of the primary infection and may remain so potentially for years or even permanently. If symptoms occur, they depend on various factors, such as the number, size, and location among other factors. Typically, hydatid disease presents with nonspecific symptoms. Common symptoms include abdominal pain, hepatomegaly, as well as anaphylaxis in case of cyst rupture. Extrahepatic intra-abdominal isolated hydatic cyst is a rare finding (6-11%).
