Hydatid disease is a zoonotic infection caused by larval stages of dog tapeworms belonging to the genus Echinococcus (family taeniidae) and is also referred to as echinococcosis. Human cystic echinococcosis caused by E. granulosus is the most common presentation and probably accounts for more than 95% of the estimated 2-3 million annual worldwide cases. The liver (70-80%) and lungs (15-25%) are...

Subendocardial hydatid . cysts may rupture into the right or left chamber of the heart to produce pulmonary or systemic embolisation.' Few cases have been reported,2 and I believe that this case is the first to be reported in the United Kingdom in which a primary hydatid cyst in the interventricular septum caused multiple emboli in the pulmonary and systemic arterial circulation. The electrocar...

Thailand is a nonendemic area of echinococcosis. We report, herein, 3 cases with a special note on the use of serology in detection of the disease in one family. All cases were Thais. The first case was a man, having a cystic mass in the liver. He was subsequently diagnosed as having echinococcosis following positive serology. The second case, a male, had a renal hydatid cyst revealed by histop...

Primary hydatid disease of the skeletal muscle without systemic involvement is rare. A 40-year-old woman presented with a painful mass in her medial left upper thigh. She was misdiagnosed as having a deep intramuscular abscess and a fine needle aspiration was performed, but the fluid came out crystal clear. Further inquiry revealed that her 16-year-old daughter had been operated on twice for li...

echinococcus granulosus is considered the major cause of human hydatid cysts. usually the duration of cyst formation is 10-20 years. this period shortens significantly upon rupture of a primary cyst. the literature describes low incidence of primary involvement of ovary as a site of hydatid cyst formation. our case is the first report on ovarian hydatid cyst in iran. a 60-year-old woman was pre...

Echinococcal disease can develop anywhere in the human body. The liver represents its most frequent location. Hepatic hydatid cysts may rupture into the biliary tract, thorax, peritoneum, viscera, digestive tract or skin. We report a rare case with rupture of the right hepatic duct into a hydatid cyst in a woman with known hydatid disease and choledocholithiasis. The increased intra-luminal pre...
