The most frequent abdominal ultrasonography findings were splenomegaly, enlarged lymph nodes, hepatomegaly and increased liver echogenicity (31.25%), (13.54%), (43.75%), (26.04%) respectively. The low frequent occurring were focal lesions in parenchymal of the organs and nephromegaly (1.04%), ascites (4.17%), portal hypertension (1.04%) and abscesses (1.04%).
