ABDOMINAL IMAGING Wandering Spleen Presenting as an Asymptomatic Pelvic Mass: A Case Report

Ectopic spleen is a rare entity. It is more common in children than in adults and it is about 15 times more common in females. Here we report a patient with an ectopic spleen who was referred for sonographic evaluation of an asymptomatic pelvic mass by a gynecologist. At sonography, a big homogenous mass located at the RLQ of the abdomen and the right pelvic cavity was detected. Further investigation by color Doppler sonography showed that the mass is an ectopic spleen and the main spleen could not be detected at its normal location. In the abdominopelvic CT scan, the spleen was located at the RLQ, no splenic tissue was found in the left hypochondrium, and this region was occupied by the left colon and stomach. Ectopic spleen, though very rare, should be considered in the differential diagnosis of asymptomatic pelvic masses.
