Primary Term Ovarian Pregnancy Superimposed by Intrauterine Pregnancy: A Case Report

Abstract

A case of primary ovarian pregnancy proceeding upto term superimposed by another intrauterine pregnancy is presented. Compound extrauterine and intrauterine pregnancy is a rare obstetric phenomenon and still rarer is a primary ovarian pregnancy proceeding upto the term. The condition was diagnosed at laparotomy during the second trimester of current pregnancy. Diagnostic laparotomy was done because the ovarian pregnancy was mimicking an ovarian tumur. The ovarian pregnancy was successfully managed by surgery. Normal vaginal delivery of a term intrauterine pregnancy occurred in due time. The difficulty of diagnosing the heterotopic pregnancy is discussed and the clinico-pathological features of primary term ovarian pregnancy is emphasized, as it is a very rare condition.

Laparoscopic Conservative Treatment of Ovarian Pregnancy and Subsequent Fertility Outcome

“…In spite of the sophisticated diagnostic tools used for the diagnosis of ovarian pregnancy, several case reports described late diagnosis of ovarian pregnancy, even in the third trimester. [7][8][9] The etiology of ovarian pregnancy is unknown. According to several publications, there is a strong relationship between ovarian pregnancy and the use of IUD.…”

Primary Ovarian Ectopic Pregnancy Misdiagnosed as First-Trimester Missed Abortion

“…[3][4][5][6][7][8] Apparently, it may also be confused with an intrauterine pregnancy. [9][10][11][12] The clinical appearance of ovarian pregnancy differs and when asymptomatic may be missed all the way until later in gestation. 12 In delaying the diagnosis, there is the danger of rupture, secondary implantation, and difficulties during surgery.…”

“…In the literature, there have been sparse case reports of primary ovarian ectopic pregnancy mistaken for intrauterine gestation, some of which progressed to the third trimester. [9][10][11][12] We present this case as an example of a misdiagnosed missed abortion and discuss sonographic examination methods to diagnose ovarian ectopic pregnancy.…”

Ovarian pregnancy: Report of four cases and review of the literature

“…The incidence of ectopic pregnancy has been reported to have increased over the last two decades, but to date, the actual etiology of ovarian pregnancy is not yet fully understood. Previous case reports of ovarian pregnancy are seen mainly in obstetrics journals, 4,6–17 and only some of these describe the histopathological characteristics of this disease 2,18–20 . Here we report four cases of primary ovarian pregnancy encountered during the last 10 years in Miyazaki prefecture, Japan, with histological characteristics and a literature review.…”
