[Pelvic splenomegaly. Ptosic, migrant or accessory spleen?].

A wandering or ectopic spleen is a rare condition in which the spleen is not located in the left upper quadrant but is found lower in the abdomen or in the pelvic region caused by improper fixation of the ligamentous attachments. Laxity of the peritoneal attachments of the spleen results in splenic hyper mobility, known as wandering spleen. Congenital and acquired causes have been advocated to explain its onset.
