Learning objectives
1) To discuss the most important abdominal manifestations of this disease.
2) To illustrate the typical and some atypical findings of schistosomiasis mansoni using different imaging modalities with pathological correlation.
Background
According to the World Health Organization (WHO),
schistosomiasis affects more than 200 million individuals distributed in 76 countries in Africa,
Asia or America and remains a major public health problem.
Adults S.mansoni reside in the venules of the intestine and the major disease manifestations are due to the deposition of eggs in the liver and the consequent liver fibrosis.
Hepatosplenic schistosomiasis mansoni is the most severe presentation of the disease,
which is characterized by extensive splenomegaly periportal fibrosis,
portal hypertension,
and upper digestive bleeding due...
Findings and procedure details
INTRODUCTION
Definition
Schistosomiasis (ie,
bilharziasis) is a human disease syndrome caused by infection from one of several species of parasitic trematodes of the genus Schistosoma.
Epidemiology
According to the World Health Organization,
schistosomiasis is a millenary disease,
which affects more than 200 million individuals distributed in 76 countries in Africa,
Asia or America (Fig.
1).
Among these,
10% present the severe form of disease and 50 to 60% of infected people,
that is more than 100 million people,
present clinical manifestations of the disease,
constituting...
Conclusion
In terms of impact this disease is second only to malaria as the most devastating parasitic disease.
Schistosomiasis mansoni is considered one of the Neglected Tropical Diseases and an awareness of the abdominal manifestations of this parasitic infection and familiarity with their expected clinical presentation and imaging findings are important for radiologists.
