Accessory spleen is a variation of spleen development.[1] The most common location of an accessory spleen is at the splenic hilum.[1,2,3] Wandering accessory spleens may mimic tumors, such as pancreatic tumor, adnexal tumor, abdominal tumor, retroperitoneal tumor, adrenal tumor, or testicular tumor, according to its location.[1,2,3,4,5,6,7] Accessory spleens are usually smaller than 3 cm. However, in this patient it is larger than 6 cm. These wandering accessory spleens are indicated for surgery when there are symptoms, such as pain, rupture, infarction, or vascular torsion.[1,2,3,4]
