Article Synopsis
- Human fascioliasis, a rare zoonotic infection in Chile, has two main clinical phases: the acute phase features symptoms like right side abdominal pain, fever, and liver enlargement, lasting between 2 weeks to 4 months.
- A case study highlights a 57-year-old woman who showed no typical risk factors or symptoms of fascioliasis but had a liver lesion diagnosed as intrahepatic cholangiocarcinoma through advanced imaging techniques.
- Upon surgical removal of the liver section, pathology revealed the presence of trematode eggs indicating fascioliasis, showcasing a potentially misdiagnosed case of a rare disease linked to Fasciola hepatica.
Introduction: The adequate treatment for hydatidosis requires a knowledge of certain aspects related to the survival of infectious agents, especially protoscoleces. The aim of this study is to evaluate the viability of protoscoleces in human hepatic hydatid cysts in order to determine the prevalence of their fertility and to study the association with variables typical of the host and of the parasite.
Materials: A cross-sectional study was done in biological material (the fluid from human hepatic hydatid cysts).
To determine the plasmatic and intracystal concentrations of albendazole sulfoxide (AS) and correlate them with the viability of the scolices in patients surgically treated for hepatic hydatid cysts (HHC) that received albendazole preoperatively, as an indirect way of evaluating the scolicide efficacy of the drug. A non-consecutive series of patients with uncomplicated HHC, underwent operation at the Department of Surgery, Regional Hospital of Temuco, Chile, between 2001 and 2002. The patients were given 10 mg/kg/day of albendazole for 4 days prior to the surgery.

Methods: Diagnostic test study. DD5, ELISA-IgG, and WB were applied in 75 patients with LE and 75 with cholelithiasis.
South Chile is an endemic zoonosis area of hydatid disease, where prevalence rates can be 30 to 40/100 000 habitants. Not only is surgery performed on a great number of liver and lung hydatid cysts every year, but also upon cysts found in uncommon abdominal locations such as spleen, peritoneum and kidney. Information on this subject is scarce.
