Ultrasound evaluation of normal splenic size in pediatric population

AbiramiMahadevan and Adaikkappan M

Background: In pediatric population knowledge of the normal splenic size and its relation to age and anthropometric parameters of growth is of importance for the determination of mild splenomegaly.
Objective: The purpose of this study is to measure normal splenic size in pediatric population of 5-15 years of age by ultrasonography and to establish correlation of the splenic size with anthropometric parameters like age, height, weight, BMI and BSA.
Study design: cross sectional research design.
Setting: Raja Muthiah Medical College, Annamalai University for a period of one year.
Participants: A total of 100 children of age 5-15 years were included. The examination was done either in a supine or right lateral decubitus position. Measurements: The splenic length was measured from the dome to the splenic tip through the splenic hilum. Demographic data were collected on each participant at the time of their pre-participation physical examination. This information included age, sex, and height and body weight. BSA and BMI were computed from measured height and weight.
Results: The mean spleen length in the pediatric population studied was 81.8 mm among the boys and 79.01 mm among the girls. There was significant relation between the spleen size and age, height, weight and body surface area.
Conclusion: The conventional method of recording splenic size by clinical examination has been reported to lack both accuracy and reliability. Our aim was to provide a more objective assessment of splenic size during routine abdominal Ultrasonogram. Our results would be used as handy, reliable normative values and is suitable for sonography units and pediatric radiology departments with a large number of patients.
