Abstract: “The present study was undertaken with an aim to evaluate the effectiveness of abdominal ultrsonography (USG) in the diagnosis of palpable abdominal mass and compare the results of USG with those of other method; whether USG can increase the diagnostic yield in case of palpable abdominal masses in paediatric age group and their consistency with histopathological diagnosis. For this purpose 30 cases were selected having palpable abdominal masses in different sites, age ranging from 6 months to 12 years. The results suggested that the predominance of male over female in the ratio of 3:2. In this study confirms that Wilm’s tumor accounted for 30.00%. In this study the sensitivity of ultrasonogram is 96.30% and the specificity is 60.00%. The positive predictive value is 92.86% and negative predictive value is 75.00% and the overall diagnostic accuracy of this series is 90.62%. In this study false positive rate of ultrasonogram diagnosis is 6.66% and false negative rate of ultrasonogram di”
