Echinococcus is a cestode. The most common Echinococcus species causing human infection are E. granulosus and E. multilocularis [1]. The commonest sites for cysts are the liver (59%–75%), followed in frequency by lung (27%), kidney (3%), bone (1%–4%) and brain (1%–2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected [2]. Multi-organ involvement without liver...

Figure 1. Noncontrast computed tomography scan of the pelvis. The arrow points to a lytic lesion in the posterior mid-right ilium characteristic of a space-occupying hydatid cyst. Diagnosis: hydatid cyst bone disease. Cysts removed from the iliac bone cavity (figures 1 and 2) were consistent with hydatid cysts due to Echinococcus species. Microscopic examination confirmed the diagnostic feature...

Hydatid cyst is a parasitic infection caused by Echinococcus granulosus, and endemic in some countries regions where the common hosts (cattle, cow, sheep) are frequently raised, such as Middle East, Australia, South America, Turkey (1). The human an intermediate host of this parasite, usually contaminated through infected foods. Liver lungs most sites hydatid whereas soft tissues rare localizat...

Hydatid disease has a worldwide distribution and causes health problems in endemic countries. Musculoskeletal hydatid disease may be a difficult differential diagnosis. The aim of this retrospective study is to present some different imaging features of musculoskeletal hydatid disease. We evaluated imaging findings of 15 patients with musculoskeletal hydatid disease over a 15-year period. Ten (...

Hydatid cyst is a disease caused by a parasitic tapeworm, Echinococcus granulosus, and most commonly involves liver and lung. Ruptured pulmonary hydatid cyst can present a diagnostic challenge, and radiograph can be inconclusive. Anaphylactic reaction is a rare complication of ruptured pulmonary hydatid cyst. A 22-year-old male came to our emergency department in shock with symptoms of shortnes...

BACKGROUND Hydatid disease is a worldwide zoonosis produced by the larval stage of cestodes of the Echinococcus genus. Hydatid disease primarily involves the liver and lungs. The brain is involved in less than 2% of cases. Surgery has long been the only choice for the treatment, but chemotherapy has been successfully replaced surgery in some special cases. CASE PRESENTATION We report a rare h...

Preparations of the two most immunoreactive Echinococcus granulosus antigens (antigens 4 and 5) from sheep hydatid fluid, purified by a simplified method, and monospecific antisera against antigens 4 and 5, prepared by a new procedure, were used to measure the antigenic concentrations of antigens 4 and 5 in swine, sheep, and human hydatid fluids from pulmonary or hepatic cysts. Two bovine sampl...

BACKGROUND Vast majority of complaints and physical examination findings of hydatid disease are common in emergency room patients. Different emergency presentations of hydatid cyst disease and their treatment are evaluated. We studied preoperative laboratory findings of these patients to identify any parameters to predict hydatid cyst-biliary system communication. METHODS We reviewed the file...

Hydatid cyst disease should be considered in differential diagnosis in many doubtful clinical situations as can present with non-specific symptoms especially in the endemic areas. Cardiac involvement should be considered in patients with history of previous hydatid cyst disease.. Cardiac hydatid cysts account for less than 2% of all hydatid diseases. In this report we aimed to present a case of...

Background: Hydatid cyst of the liver may be complicated by spontaneous rupture into the biliary tract with biliary obstruction. Methods: ERCP of hydatid cyst liver with biliary communication was done and bile duct cleared and cyst was assessed for resolution. Results: A 56 year lady who had jaundice, right upper abdomen pain and cholangitis was diagnosed to have hydatid cyst of liver with bili...
