Hydatid disease (cystic echinococcosis) is a zoonotic infection caused by larval forms of the tapeworm Echinococcus granulosus. Most common site for cysts is liver and hepatic hydatidosis has a diverse clinical spectrum. Mostly they remain asymptomatic and uncomplicated. Here we report a case of a 50 yr old farmer admitted for renal disease, who was incidentally found to have inferior vena cava...

Natural infection with larval Echinococcus multilocularis was recognized in one of eight Norway rats, Rattus norvegicus, caught indoors in 2009 in Ebetsu, Hokkaido, northern Japan. Cystic lesions were found in the right median and lateral lobes of the liver, with numerous alveolar cysts in the periphery of the lesions. Protoscolices were formed within large cysts. The laminated layers of the cy...

Hydatid disease is a parasitic infection that is remains endemic in many countries, particularly the Middle East and Central Asia. Mediastinal hydatidosis is very rare (less than 0.1% of all hydatid disease cases) that have been only anecdotally in the literature. To the best of our knowledge only one case of multiple mediastineal hydatid cysts has been reported previously. We report the second...

Alveolar and cystic hydatidosis are caused by infection with the larval stages of Echinococcus multilocularis and Echinococcus granulosus, respectively. A host-protective antigen has been identified in E. granulosus. Here we identify the presence of a closely related protein in E. multilocularis, characterize and express a cDNA encoding the antigen (designated EM95), determine the structure of ...

Cystic disease of the spleen is an uncommon entity in general population. Most cases result from parasitic infection by Echinococcus granulosus, a form called splenic hydatid disease (SHD), with a reported frequency of 0.5-6.0% within abdominal hydatidosis. On the contrary, an isolated splenic involvement of hydatid disease is very uncommon even in endemic regions. Two cases of primary SHD mana...

A 28-year-old female patient was referred to us with complaints of massive haemoptysis and cough with expectoration, of two years' duration. Her chest radiograph, computed tomography scan and video-bronchoscopy revealed a cystic lesion in the right upper and lower zones of the lungs. Aspiration from the cyst fluid was grossly hemorrhagic and full of inflammatory cells. On digestion of the fluid...

The sartorius muscle is a rare location of primary hydatid cyst. In this report, the clinical, pathologic, and radiologic features are discussed, with special emphasis on the pathologic and radiographic features. We report a case of hydatid cyst of the proximal thigh in an eight-year-old girl. Magnetic resonance (MR) images revealed muscular hydatid cyst in the sartorius muscle, with a striking...

BACKGROUND Hydatidosis is a zoonotic disease of global prevalence. It causes considerable health problems and economic losses throughout the world, including Iran. The objective of this study was to assess the current status of echinococcosis/hydatidosis in the province of Ilam (western Iran). METHODS From April to September 2011, 65 stray dogs were collected from urban and rural areas of Ila...

Echinococcosis (hydatidosis) remains a crucial public health concern in areas of endemicity including South Sudan. It affects mostly liver and lungs but rarely musculoskeletal system. A female, aged 75 years, presented to Kapoeta State Hospital, with three years’ history painless mass on her back, gradual onset. There was no trauma, pain or fever. On examination there 8cm x 5cm, soft, non-tende...
