The accuracy of ultra-sonographic findings in detection of abdominal tumor size in children (our experience in Children Medical Center)

Since the abdominal tumors are one of the common causes of childhood death,studying theclinico-pathologic features of tumors is important for early diagnosis. The aim of this study was to determine these features in Iranian children and to evaluate the accuracy of Ultrasonography in determining the abdominal masses in children.
In this retrospective case series study data about the sex, age, primary chief complaint, physical examination, imaging report, Pathology finding of 156 children with abdominal tumor, who admittedtothe childrenmedical centerin last 6 years.
Male to female ratio was 0.69. The most common type of tumor in this study wasWillm’s (37.5%) and Neuroblastoma (35.7%). The mean age in children with Willm’s tumor and Neuroblastoma was 38.95 and 26.65 months old respectively.Ultrasonographyhas lower accuracyin patients with tenderness, children with Willm’s tumor, female patients and children under 5 years old.
The observed differences in tumor type and distribution in comparison with previous studies may be attributed to genetic and geographic variations. In addition, this study shows that the accuracy of Ultrasonography in children with abdominal tumors depends on children’s sex, age, pain and type of tumor.
