# Renal Artery Aneurysm Rupture as a Dangerous Mimic of Ovarian Cyst Rupture: A Case Report

## TL;DR

A rare case of a ruptured kidney artery aneurysm was mistaken for an ovarian cyst rupture, highlighting the need for quick CT scans in similar cases.

## Contribution

This case report highlights the importance of considering renal artery aneurysm rupture in the differential diagnosis of hemoperitoneum.

## Key findings

- A woman with a history of ovarian cysts was diagnosed with a ruptured renal artery aneurysm.
- Prompt CT imaging and emergency surgery led to successful treatment and recovery.

## Abstract

Renal artery aneurysm rupture is a rare but morbid diagnosis, often requiring emergency surgery and nephrectomy. Clinical presentation can mimic more common pathology in non-pregnant women such as ruptured ovarian cyst.

We present a case of a woman with a prior history of ovarian cyst presenting with a ruptured renal artery aneurysm. Prompt computed tomography (CT) imaging revealed a left renal artery aneurysm rupture with hemoperitoneum and renal infarct. She underwent emergency laparotomy and nephrectomy and was ultimately discharged in good condition.

While ovarian cyst rupture is the most common cause of spontaneous hemoperitoneum in non-pregnant women of childbearing age, renal artery aneurysm rupture should be considered and prompt CT imaging obtained, particularly in cases of hemodynamic instability, to ensure prompt treatment.
