Hydatid cyst, the larval stage of Echinococcus spp., is a common parasitic disease in Iran. The liver and the lungs are the most commonly involved organs. Hydatid cysts have also been reported in bones and soft tissues such as muscle, brain tissue, spleen, thyroid and even in the heart. Hydatid cyst of the inguinal area, resembling a hernia is a rarity presenting at an unusual site. A hyper...

Musculoskeletal system is rarely involved by hydatid cyst,the larval form of Echinococcus Granulosus. A 37-year old man was diagnosed as having a cystic mass within his left thigh musculature. Preoperative computerized tomography suggested an unusual location of echinococcus although serology could not confirm the diagnosis. During surgery, a white coloured cyst within left vastus lateralis mus...

Hydatid disease is caused by an infestation with the tapeworm Echinococcus. Each parasite can produce thousands of eggs with oncospheres that can migrate to the liver or lungs and rarely to other sites, including muscles. The aim of this case study is to describe a rare case of a patient with an atipical hydatid cyst location and to raise awareness of this condition. We present the case of a 28...

Echinococcus granulosus causes a zoonotic infection called Cystic Echinococcosis (CE). Surgeons meet with hydatid cysts of the liver and lungs with reasonable frequency. However hydatid cyst may also appear in other parts of the body. A 30 years old lady presented with a smooth slow-growing subcutaneous nodule on the anteromedial side of the right thigh with no detectable primary site in the li...

Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced c...

Cystic echinococcosis (CE), also known as "hydatid disease" (HD), is a zoonotic infection caused by the larval stage of Echinococcus granulosus, which infects humans as intermediate hosts through the orofecal route. Carried by the intestinal venous blood, the embryos released by the eggs of the tapeworms can reach every organ, especially the liver, turning into a hydatid cyst. Usually asymptoma...

Echinococciasis is a zoonotic infestation, which generally involves the liver and the lungs. Primary muscle hydatidosis is an uncommon finding. The authors report a case of primary hydatid cyst localized in the right long head of the biceps femoris of a 25-year-old woman. A wide excision of the cyst with a safety margin was performed. No recurrence has been detected after a 3-year follow-up per...

HYPOTHESIS The prediction of an intrabiliary rupture of a hepatic hydatid cyst using associated clinical factors is important for early diagnosis and proper management. DESIGN Case series of patients with hepatic hydatid cysts treated between January 1, 1992, and January 1, 2000, in a single institution. SETTING A tertiary care teaching hospital. PATIENTS The clinical findings in 116 pati...

Hydatid cysts rarely appear isolated in the orbital cavity without involvement of other organs. The cysts are usually located in the retrobulbar region, and may be extraconal or intraconal. Herein we present a case of primary orbital cyst hydatid that is adjacent to the medial rectus muscle and optic nerve in the intraconal space and the difficulties during the surgical and medical treatment pe...

Cardiac hydatid cyst is an uncommon but potentially fatal disease. In cystic Echinococcus humans are an accidental host. Liver and lungs are the most frequently involved organs. Herein a unique case of intramyocardial hydatid cyst of left ventricle along with pulmonary hydatid cyst in a 38-year-old lady is reported. Surgical removal of the cardiac hydatid cyst was done with the aid of cardiopul...
