Abstract
Variations in shapes and morphometry of spleen is seen. Number and location of splenic notches show regional variation. This study is done to determine tools for sexual dimorphism of spleen. 72 spleen of known sex were used from cadavers used for 1st MBBS dissection. Shape, number and location of splenic notches were noted. Length, breadth, thickness and weight of spleen were calculated. Triangular shaped spleen was seen most commonly. Maximum 5 notches were seen on a spleen. Morphometric measurements showed regional variations and sexual dimorphism. We conclude that formation of splenic notches by incomplete fusion of various lobes has been mentioned in earlier embryological studies but new hypothesis suggests that these notches can be considered developmental variations. A wide variation in shapes and morphometrics of spleen is seen. They can be used as tools of sexual dimorphism.
