IntroductionHydatid cyst is a parasitic disease commonly observed in developing countries, where agriculture and animal breeding are widespread, and preventive medicine is not sufficient. Its incidence in Turkey is 2 in 100,000 people (Tatar et al., 2003).Hydatid cysts are caused by Echinococcus granulosus. Although the adult form of the parasite develops in the small intestine of main hosts carnivores such as dogs, wolves, and jackals. The larvae of the parasite settle in different organs of intermediate host herbivores such as cattle, sheep or goats, and humans and cause unilocular cystic Echinococcosis. When ingested by humans, the larval form of the parasite is broken down in the stomach, and the released embryo reaches the liver through the portal system. The disease is observed mostly in the liver (60%), which has a rich capillary network. Embryos that have passed the liver arrive in the right side of the heart via hepatic veins and the vena cava, ultimately reaching the pulmonary capillaries, where they embed themselves and cause the disease in the lungs (30%). Embryos that have entered the systemic circulation and cause the disease in other organs (10%) (Yüksel ve Kalaycı, 2001;Kılıç et al., 2010).
Materials and methodsEighty patients treated and followed in our clinic for hydatid cyst between 2001 and 2011 were retrospectively studied. All of the patients were examined with chest X-Ray, computed tomography and ultrasonography. While the localizations of hydatid cysts of lung and liver were determined by using computed tomography (CT) and ultrasound (USG), for cardiac hydatid cysts, echocardiography and magnetic resonance imaging MRI were used. Twenty-four patients with multiorgan hydatid cysts were studied for the symptoms, localizations of cysts, complications and results of medical and surgical treatment.
ResultsOf the patients, 12 were female and 12 were male. The mean age was 35 (13-76) years. The most common symptoms were
