Accessory spleen usually measures 1 cm in diameter, but its size varies from a few milimeters to centimeters. Also the number of accessory spleens can vary from one to six . Accessory spleens are usually incidentally detected and asymptomatic, but in case of unexpected locations, accessory spleen can be of clinical impoance. Ref - radiologyassistant.com
