Different aspects of hepatosplenic schistosomiasis are revisited here. Manson's schistosomiasis causes periportal fi brosis and portal hypertension in approximately 6% of infected subjects, usually with preservation of their hepatic function. The assessment of liver involvement is of major importance in determining the prognosis and risk of complications from schistosomiasis, such as upper digestive bleeding secondary to variceal rupture. For many years, the diagnosis of hepatosplenic schistosomiasis and liver fi brosis was made by abdominal palpation and the fi nding of liver and/or spleen enlargement. However, there is no consensus regarding the clinical parameters of the liver and spleen to be considered in this physical evaluation. For the last three decades, abdominal ultrasound (US) has become the best imaging technique to evaluate liver fi brosis caused by schistosomiasis mansoni. However, US is a subjective procedure and is therefore examiner-dependent. Magnetic resonance imaging (MRI) fi ndings have provided valuable information in addition to ultrasound and clinical examination. The combination of a comprehensive history and physical examination, basic laboratory tests (a stool examination for Schistosoma mansoni eggs and a blood cell count), biomarkers for liver fi brosis/portal hypertension and imaging methods seem to offer the best approach for evaluating patients with this disease. In situations where research is involved or in patients with severe disease, MRI may be considered.

“…The diagnosis was based on the following criteria: epidemiological evidence, contact with stream water from endemic areas, clinical evidence (hepatomegaly and splenomegaly), portal hypertension, esophageal varices diagnosed during upper digestive endoscopy, Schistosoma mansoni eggs in the stools, and ultrasound or magnetic resonance imaging showing characteristic Symmers' fibrosis of the liver and significant portal vein collaterals. 17,18 All of the patients had three negative parasitological stool examinations using the Kato-Katz technique, 19 and they also reported previous treatment of schistosomiasis ranging 2-5 years before enrollment in the study.…”

Abstract. We investigated the serum and urine chemokine levels of patients with schistosomal mansoni glomerulonephritis. This cross-sectional study was conducted in the Southeast of Brazil. Overall, 160 subjects were enrolled and divided into five groups: 1) hepatosplenic schistosomiasis with renal disease (N = 12); 2) hepatosplenic schistosomiasis without renal disease (N = 68); 3) hepatointestinal schistosomiasis (N = 27); 4) glomerulopathy caused by other diseases (N = 22); and 5) healthy controls (N = 31). The patients with microalbuminuria 30 mg in 24 hours were considered to have renal disease. The sera and urine chemokines CCL2, CCL3, CCL5, CCL11, and CXCL8 were measured using an enzyme-linked immunosorbent assay test. A similar profile was observed between the patients with schistosomal glomerulopathy and the patients with glomerulopathy caused by other diseases, with the exception of serum CCL2 634.3 pg/mL. In cases with sera CCL2 634.3 pg/mL, the diagnosis of schistosomal glomerulopathy should be considered.

“…MR can also show fat hypertrophy around the hepatic hilum and gallbladder fossa with intrahepatic extension of the fat. Chronic hepatopathy and portal hypertension features can also be seen [82, 90, 91]. The fibrotic septa of S. japonicum are hypointense on T1WI and hyperintense on T2WI [4].…”

Unexpected hosts: imaging parasitic diseases

et al. 2016

View full text Add to dashboard Cite

Radiologists seldom encounter parasitic diseases in their daily practice in most of Europe, although the incidence of these diseases is increasing due to migration and tourism from/to endemic areas. Moreover, some parasitic diseases are still endemic in certain European regions, and immunocompromised individuals also pose a higher risk of developing these conditions. This article reviews and summarises the imaging findings of some of the most important and frequent human parasitic diseases, including information about the parasite’s life cycle, pathophysiology, clinical findings, diagnosis, and treatment. We include malaria, amoebiasis, toxoplasmosis, trypanosomiasis, leishmaniasis, echinococcosis, cysticercosis, clonorchiasis, schistosomiasis, fascioliasis, ascariasis, anisakiasis, dracunculiasis, and strongyloidiasis. The aim of this review is to help radiologists when dealing with these diseases or in cases where they are suspected. Teaching Points • Incidence of parasitic diseases is increasing due to migratory movements and travelling. • Some parasitic diseases are still endemic in certain regions in Europe. • Parasitic diseases can have complex life cycles often involving different hosts. • Prompt diagnosis and treatment is essential for patient management in parasitic diseases. • Radiologists should be able to recognise and suspect the most relevant parasitic diseases.
