Echinococcus vogeli has been reported to cause human polycystic echinococcosis. A 43-year-old Brazilian woman was admitted to hospital complaining of mild epigastric discomfort. Computed tomography (CT) revealed multiple cystic lesions with calcified edges in several hepatic segments. At exploratory laparotomy, polycystic lesions were excised from the(More)
Echinococcus vogeli is known to occur in the neotropics, causing polycystic echinococcosis (PE) in humans. The liver and lungs are the most commonly affected organs. In this paper, we report six cases of human PE in the mesenteries without primary liver involvement. All patients, four males and two females (median age 34 years; range 20-48 years), lived in(More)
To date, nothing is known about the genetic diversity of the Echinococcus neotropical species, Echinococcus vogeli and Echinococcus oligarthrus. Here we used mitochondrial and nuclear DNA sequence polymorphisms to uncover the genetic structure, transmission and history of E. vogeli in the Brazilian Amazon, based on a sample of 38 isolates obtained from(More)
CONTEXT Orthotopic liver transplantation (OLT) is the treatment of choice for end-stage liver disease. Cirrhosis due to hepatitis C infection is the leading indication for liver transplantation worldwide. However, patients who are given transplants because of viral liver diseases often present clinical coinfections, including hepatitis B together with(More)
Neotropical polycystic echinococcosis (NPE) is a parasitic disease caused by cestodes of Echinococcus vogeli. This parasite grows most commonly in the liver, where it produces multiples cysts that cause hepatic and vessel necrosis, infects the biliary ducts, and disseminates into the peritoneal cavity, spreading to other abdominal and thoracic organs.
