Ultrasonic Diagnosis and Differential Diagnosis of Abdominal mass of Children

Objective To study ultrasonic diagnosis and differential diagnosis of abdominal mass of children through the analysis of ultrasonography of abdominal mass of 78 children. Methods Studying ultrasonographic features and diagnostic characteristics of abdominal mass of children based on the retrospective analysis of ultrasonography and comparison with the result of operation, pathology and cytological examination of abdominal mass of 78 children. Results In all cases, non-tumorous masses were 31 cases (39.7%) and tumorous masses were 47 cases (60.3%). Among the tumorous masses, malignant tumors were 44 cases, making up 93.6%, and 56.4% of all cases. The ultrasonic diagnosis coincidence rate was 79.5%, compared with pathological diagnosis. Accurate rate of localizing diagnosis of ultrasonography was 92.3% according to operation. Obscure diagnosis and misdiagnosis were 12 and 4 cases respectively.Conclusions Ultrasonography could indicate focus size, sites, origin, property, relation with adjacent organs and whether metastatic focuses and complication exist, and it is one of the important methods in examining abdominal mass of children.
