title: Imaging the effects of an ectopic spleen on the urinary tract.
abstract: A 75-year-old woman with chronic lymphocytic leukemia who presented clinically with urinary frequency was found on physical examination to have a pelvic mass. Ultrasound and computed tomography showed it to be due to a large ectopic spleen lying in the pelvis behind the bladder and compressing it anteriorly. The spleen became smaller and the symptoms regressed with chemotherapy. We review the features of an ectopic spleen as seen on diagnostic imaging studies.
