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...

BACKGROUND Hydatid disease (HD) is a cosmopolitan parasitosis caused by Echinococcus granulosus that can potentially affect any part of the human body. Liver and lungs are the most frequent localizations. Primary musculoskeletal hydatidosis are seldom reported in literature and their incidence is unknown. CASE PRESENTATION We deem interesting to report a case of a primary hydatid cyst in a 25...

Hydatid cyst is a parasitic disease that is endemic in Mediterranean areas, South America, North Africa, Australia, and Iran. Although the liver and lung are the most common involved organs, but the other organs in human body also can be involved by hydatid cyst. Chest wall involvement by hydatid cyst is a rare condition, which may be misdiagnosed as chest wall tumor in the endemic areas. Herei...

Echinococcosis a zoonotic infection caused by echinococcusgranulosus is still a large extended public health problem in endemic regions. Primary echinococcosis may develop in almost any organ or tissue. The liver and the lungs are the most frequently involved organs. Primary hydatidosis of soft tissue involving foot, coccygeal region and breast is extremely rare even in endemic areas. After dia...

Splenic Hydatid Cyst is a very rare presentation with less than 5% of total incidences Cystic Echinococcosis. It usually due to spread cysts from other regions leading secondaries. Primary isolated splenic hydatid cyst without involvement any organs even rarer. We report an unusual case female who presented as Abnormal Uterine Bleeding (AUB) incidental finding Isolated absence organ. Patient un...

Collapsed membranes and daughter cysts are pathognomonic for hydatid cysts on imaging. The comma-shaped lesions, visible within the hydatid cyst in sagittal view of MRI, are collapsed membranes. Although primary hydatid cyst of pelvic cavity is rare, clinicians should remember to include hydatid cysts in differential diagnosis of pelvic cysts.

Hydatid cyst disease (Echinococcosis) is a parasitic illness that is rarely located in the brain. Primary cerebral hydatid cyst disease is rarely seen. We report here rare two cases presenting with sixth cranial nerve palsy with increased intracranial pressure syndrome due to primary cerebral hydatid cyst. A 5-year-old female and a 13-year-old boy complained of headache, strabismus, nausea, and...

BACKGROUND Hydatid disease is a life-threatening parasitic infestation caused by Echinococcus granulosus. Infection with E. granulosus typically results in the formation of hydatid cysts in the liver, lungs, kidney, and spleen. Primary intracranial hydatid cyst disease is extremely rare. Here, we are reporting an unusual case of Echinococcus, where the only identifiable lesion was a hydatid cys...

Hydatid cyst is a zoonotic disease that is common in the Mediterranean region. Thoracic wall, rib or extrapulmonary intrathoracic localization of the cysts is very rare. Giant extrapulmonary intrathoracic hydatid cysts can lead to both diagnostic and treatment difficulties and can be confused with tumor. We present a case of a hydatid cyst with thoracic wall involvement mimicking tumor. We conf...

○ INTRODUCTION Hydatidosis is a silent, cyclozoonotic and oldest infection of man and domestic animals and is caused by larvae of the cestode, Echinococcus (Bhatia and Pathak, 1990). The infected human beings and animals loose their normal functional capacities leading to huge economic losses. The diagnosis of hydatid disease is based on clinical, radiological, microscopical and immunological m...
