Primary twin ovarian pregnancy: Case report and review of the literature

Abstract

Primary twin ovarian pregnancy is extremely rare. We present one such case in a 25-year-old primigravida who complained of lower abdominal pain and mild vaginal bleeding at 8 weeks after her last menstrual period. Transvaginal sonography revealed an empty uterus and presence of a gestational sac containing 2 dead embryos in the right ovary. The patient underwent unilateral oophorectomy, and histologic studies confirmed a uniovulardiamniotic ovarian pregnancy. A brief review of the literature revealed that primary ovarian pregnancy may occur without any classical antecedent risk factors, and endovaginal sonography can be useful to establish early preoperative diagnosis of ectopic ovarian pregnancy.

Editorial: Lessons from a case of tubal twin pregnancy

“…The commonest site of tubal pregnancy is the ampulla followed by isthmus, with the fimbria being involved in only 5 -11 % of cases (Almeida, 2011). The location of the present case in the relatively unusual position is concordant with reports of twin pregnancy in rarer tubal sites like cornual (Ragsdale et al, 2014) and in other ectopic positions including the cervix (Pascual et al, 2001), ovary (Garg et al, 2009) and abdomen (Mpogoro et al, 2013). This calls for thorough examination of the abdomen and pelvis when scanning for ectopic pregnancy.…”

Spontaneous Caesarean scar associated with ectopic tubal twin pregnancy: a case report and review of the literature

“…There are comparatively more reports of ectopic twin pregnancy in the same or contralateral fallopian tubes, and it is more commonly seen after assisted reproduction [3,4]. There are also some reports of ovarian ectopic twin pregnancy [5], cornua uteri ectopic twin pregnancy [6], and CSP associated with cornua uteri ectopic pregnancy [7]. The current case was particularly rare because it was a spontaneous CSP associated with ectopic tubal twin pregnancy, of which only one case has been reported to date [8].…”

Twin tubal pregnancy: A large unruptured ectopic pregnancy

“…Akin to singleton ectopic, fallopian tube is the most common site of involvement. Other reported sites include ovary, broad ligament, cervix and the interstitial part of the uterus . Abdominal and cesarean scar twin ectopic pregnancy and occurrence as heterotropic pregnancy with a coexisting intrauterine pregnancy have also been described .…”

“…Other reported sites include ovary, broad ligament, cervix and the interstitial part of the uterus. [5][6][7][8] Abdominal and cesarean scar twin ectopic pregnancy and occurrence as heterotropic pregnancy with a coexisting intrauterine pregnancy have also been described. [9][10][11] The risk factors include infertility treatment, pelvic infection and tubal surgery.…”
