“…The kidneys are the most frequently involved organs, and their involvement is thought to be due to the dissemination of the parasite through the portal venous system and retroperitoneal lymphatics to reach the renal fossae (40). The bladder, seminal vesicles, prostate glands, ovaries, and uterus also can be affected-sometimes in isolation without coexisting upper genitourinary HD; this condition is sometimes referred to as pelvic echinococcosis (41). Most cases of pelvic HD develop from peritoneal spreading or hematogenous or lymphatic dissemination; anterograde bladder seeding from contaminated urine is a rare cause of this infection.…”

Imaging of Hydatid Disease with a Focus on Extrahepatic Involvement

et al. 2017

Hydatid disease (HD) is a parasitic infection caused by the larvae of a tapeworm that is endemic to many regions around the world-South America, Africa, and Asia, in particular. Humans are infected as intermediate hosts in the parasite's life cycle; thus, HD can be seen in persons living in areas where animal husbandry is practiced. However, owing to the varied patterns of migration and immigration during the past several decades, HD can be diagnosed in individuals living anywhere. The liver is the most common organ involved, with hepatic HD accounting for the majority of published cases. However, HD can affect multiple organs and tissues other than the liver, including the spleen, kidneys, lungs, heart, peritoneum, muscles, and brain. Knowledge of the route of spread, clinical findings at presentation, and possible complications involving each extrahepatic location can be useful for the radiologist when evaluating imaging findings in patients suspected of having HD. The ultrasonographic, computed tomographic, and magnetic resonance imaging findings of extrahepatic hydatid lesions frequently simulate those of hepatic HD, as long as rupture, bleeding, and/or superimposed bacterial infection has not occurred. Specific features of HD seen at different extrahepatic sites can help tailor the diagnosis. The differential diagnoses that can mimic HD at every nonhepatic location should be considered, as many of these entities are common, especially in nonendemic areas. RSNA, 2017.

“…The location of RVHC can be subdivided into two categories, those developing chiefly in the greater peritoneal or abdominal cavity (cited as intraperitoneal type: 18 cases), and the others chiefly in the confined pelvic or lesser peritoneal cavity (cited as subperitoneal type: nine cases); the subperitoneal type was more liable to induce ureteral compression and more difficult to approach surgically . The predominant symptom due to RVHC was burning micturition (13 cases); physical examination revealed a pelvic mass in 17 patients and preoperative diagnosis was based on intravenous pyelography, ultrasonography (see also Ranzini et al 2002), CT (see also Yilmaz et al 2002), and serologic tests.…”

This paper reviews the literature on zoonotic cestode infections with specific reference to the years 1999-2003. The sources and prevalence of various zoonotic tapeworm infections caused by adult and larval stages of the genera Taenia, Echinococcus, Diphyllobothrium, Hymenolepis and Dipylidium continue to be an important cause of morbidity and mortality, not only in most underdeveloped countries but also in industrialized countries, particularly in rural areas or among immigrant groups from endemic areas. The review gives a detailed report on recent molecular epidemiological studies on the taxonomy and phylogenetic variations in Echinococcus granulosus, immunological tests and imaging techniques used in epidemiological surveys and clinical investigations of important adult and larval tapeworm infections of animals and humans. Larval stages or metacestodes of Taenia solium, Echinococcus spp. and pseudophyllidean tapeworms (Spirometra syn. Diphyllobothrium spp.) may reside in various tissues of their intermediate hosts, including humans. In particular, Cysticercus cellulosae (T. solium) and the larvae of E. granulosus, and E. multilocularis, which are predominantly located in the liver, lungs and central nervous system forming various types of cysts, lead to a complex of systemic diseases such as cysticercosis, cystic echinococcosis and alveolar echinococcosis, respectively. Relatively rare clinical manifestations are seen in the muscles, subcutaneous tissue, spleen, kidneys, bones and body cavities.

Coexistent borderline serous cystadenoma with multifocal hydatidosis in a young female: lessons learnt

et al. 2016

Hydatid disease (HD) is a commonly occurring zoonotic disease caused by tapeworms of the genus Echinococcus. It is endemic in many parts of the world and can involve almost any organ of the body. Although HD of the liver and lungs is quite common, ovarian involvement is rare. We present a case of a 24-year-old female patient who was diagnosed with multifocal hydatidosis involving the liver and bilateral ovaries on imaging. Postoperative histopathology confirmed the hydatid disease in the liver and one ovary. However, the cystic lesion in the other ovary turned out to be a borderline serous cystadenoma. This case highlights the limitation of imaging in differentiating between simple hydatid cysts and serous cystadenomas of the ovaries. Another point we learnt is that even in the presence of multifocal hydatidosis in endemic regions, serous cystadenoma needs to be considered in imaging differential diagnosis.
