Wandering spleen as an asymptomatic pelvic mass.

Background: Wandering spleen is caused by laxity of the ligaments surrounding the spleen and may present as an asymptomatic pelvic mass.
Case: A 20-year-old woman with a neurogenic bladder was diagnosed with a pelvic mass on a routine screening ultrasound. The mass was described as solid and multilobulated, with the lobules measuring up to 5 cm in diameter. She was completely asymptomatic. Exploratory laparotomy revealed a wandering spleen.
Conclusion: Wandering spleen, though unusual, should be included on the differential diagnosis of patients with an asymptomatic solid pelvic mass.
