Ectopic ovarian pregnancy diagnosed in the second trimester of pregnancy in a patient with an IUD

Primary ovarian location is a rare form of ectopic pregnancy. According to the existing literature, the presence of an intrauterine device is its main risk factor. Its preoperative diagnosis is difficult and is usually confirmed during surgery or through subsequent histological study. Most ovarian pregnancies end in the first trimester of gestation. Those reaching the second trimester without rupture-as in the clinical case that we describe below-remain an exception. In the case of a suspected diagnosis, urgent surgical treatment is recommended to prevent rupture of the ovarian ectopic pregnancy. (C) 2021 Elsevier Espana, S.L.U. All rights reserved.
