# Early first trimester diagnosis and management of rudimentary horn pregnancy: A rare case report

## TL;DR

A rare case of rudimentary horn pregnancy was diagnosed early and successfully treated with surgery to prevent life-threatening complications.

## Contribution

This case report adds to the limited literature on early diagnosis and management of rudimentary horn pregnancy.

## Key findings

- Early diagnosis via pelvic ultrasound and confirmation by laparoscopy prevented severe complications.
- Surgical resection of the rudimentary horn resulted in an uneventful recovery.
- Prompt intervention is crucial to avoid uterine rupture and placenta accreta.

## Abstract

Rudimentary horn pregnancy (RHP) is a rare and potentially life-threatening form of ectopic pregnancy that occurs in the context of a unicornuate uterus resulting from incomplete development of 1 Müllerian duct. We present the case of a 31-year-old nulligravida woman diagnosed at 8 weeks and 2 days of amenorrhea with an RHP, initially suspected via pelvic ultrasound and confirmed by laparoscopy. The patient underwent surgical resection of the rudimentary horn containing the pregnancy, with an uneventful postoperative course. RHP often presents with nonspecific symptoms, making early diagnosis difficult, and carries a high risk of uterine rupture and placenta accreta if left untreated. This case highlights the critical role of early ultrasonographic evaluation and emphasizes the importance of prompt surgical intervention to prevent severe maternal morbidity.
