“…However, the quantitative assessment of periportal thickness of portal vein walls, particularly of the secondary branches, proved to be difficult in everyday use. In addition, it is considered time-demanding and complex, leading to low reproducibility , Hoffmann et al 2001, Richter et al 2001, Ruiz et al 2002, King et al 2003.…”

“…For the last 20 years, abdominal ultrasound (US) has become the best tool for the evaluation of liver fibrosis in schistosomiasis mansoni (Lambertucci et al 1996, Richter et al 2001.

For the last two decades, ultrasound (US) has been considered a surrogate for the gold standard in the evaluation of liver fibrosis in schistosomiasis. The use of magnetic resonance imaging (MRI) is not yet standardised for diagnosing and grading liver schistosomal fibrosis. The aim of this paper was to analyse MRI using an adaptation of World Health Organization (WHO) patterns for US assessment of schistosomiasis-related morbidity. US and MRI were independently performed in 60 patients (42.1 ± 13.4 years old), including 37 men and 23 women with schistosomiasis. Liver involvement appraised by US and MRI was classified according to the WHO protocol from patterns A-F. Agreement between image methods was evaluated by kappa index (k). The correlation between US and MRI was poor using WHO patterns [k = 0.14; confidence interval (CI) 0.02; 0.26]. Even after grouping image patterns as "A-D", "Dc-E" and "Ec-F", the correlation between US and MRI remained weak (k = 0.39; CI 0.21; 0.58). The magnetic resonance adaptation used in our study did not confirm US classification of WHO patterns for liver fibrosis

“…The most important fi ndings are echogenic thickening of the walls of the portal vein and its branches, indicative of periportal fi brosis, and echogenic enlargement of the gallbladder wall. However, US is a subjective procedure and is therefore examiner-dependent [23][24][25][26][27][28][29][30][31][32] .…”

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.

“…More objective criteria to evaluate liver fibrosis and portal hipertension in schistosomiasis mansoni, using US, appeared in 1996 and were revised in 2000: the evaluation of portal and splenic vein diameters, the disclosure of collateral veins, the diagnosis of ascites, the measurement of the wall of portal branches, the sizes of liver and spleen, the identification of gallbladder wall thickening, and the image patterns of the liver (Richter et al 2000(Richter et al , 2001.…”
