# Primary Ovarian Pregnancy: A Case Report With a Review of the Literature

## TL;DR

This paper presents a rare case of ovarian ectopic pregnancy in a young woman with no risk factors, highlighting the difficulty in diagnosing such cases before surgery.

## Contribution

The paper contributes a unique case of ectopic ovarian pregnancy without traditional risk factors, emphasizing diagnostic challenges.

## Key findings

- Ectopic ovarian pregnancy is rare and often misdiagnosed as other gynecological conditions.
- Histopathological examination is required for a definitive diagnosis of ectopic ovarian pregnancy.
- The case highlights the absence of traditional risk factors in some ectopic ovarian pregnancy cases.

## Abstract

Ectopic pregnancy (EP) constitutes 1%-2% of all pregnancies and is one of the leading causes of maternal morbidity and mortality. The most common site of ectopic pregnancy is the ampulla. Ectopic ovarian pregnancy (EOP) is one of the rare events, with an incidence of 0.5%-3% of all pregnancies. The incidence is higher in intrauterine device users or assisted reproductive techniques. The precise aetiology and pathogenesis of EOP remain elusive. Clinically, EOP mirrors the presentation of tubal pregnancy or a ruptured luteal cyst, often leading to life-threatening hypovolemic shock. Transvaginal sonography is the primary diagnostic tool. Still pinpointing the exact location early on poses challenges, and it’s usually misinterpreted as a tubo-ovarian mass, hemorrhagic cyst, or luteal cyst. Furthermore, while a suboptimal rise in serum beta-human chorionic gonadotropin (β-hCG) levels may indicate pregnancy, it doesn't definitively confirm EOP. Only histopathological examination offers a conclusive diagnosis. This paper discusses an EOP case in a young woman who experienced five months of amenorrhea and exhibited no traditional risk factors, underscoring the significant challenges inherent in preoperative diagnosis.
