Management of the patient with an intrauterine device and a unilateral adnexal mass.

Patients wearing the intrauterine contraceptive device (IUD) and presenting with an unilateral adnexal mass may have a pelvic abscess in the absence of the typical dramatic stigmata that usually accompany an acute pelvic infection. Three such patients are presented, each receiving a different surgical management. An elevated erythrocyte sedimentation rate helps make the diagnosis in these relatively asymptomatic patients. IUD removal and prompt hospitalization for intravenous antibiotics are the appropriate management.
