Introduction: The spleen is the largest organ in the reticuloendothelial system; it shows variations in size and weight at different periods of life in different individuals in different conditions. The spleen, normally lies entirely within the rib cage, has a maximum cephalocaudal diameter of 13 cm by ultrasonography or maximum length of 12 cm by radionuclide scan, and is usually not palpable. Only 10- 15% of normal spleen is palpable. Aim: To study the splenic length by ultrasonography in relation to height of adult population. Material and Methods: A prospective study was conducted on 300 individuals, 150 males and 150 females, aged between 20-60 years. USG was done by using ESAOTE MY LAB 40 machine in Radiology Department Sir T Hospital Bhavnagar. Measurement of spleen was taken by using convex 2.5-6.6mhz probe. Individual was positioned on couch in supine and right lateral position for examination with deep inspiration. Spleen length was measured on longitudinal coronal image from dome to tip through hilum. The height of patient was recorded by Stadiometer with accuracy of 0.1 cm. Results: The study shows the splenic length increased with height in both male and female. The length of the spleen was less in females than males with each corresponding groups of height. Conclusion: This study provides the information that splenic length increases with the increase in the height, in both male and female.
