# Silent Threat: Bilateral Giant Asymptomatic Endometriotic Cysts With Unilateral Sudden Rupture—A Case Report

## TL;DR

A rare case of large, silent endometriotic cysts rupturing suddenly in a young woman, requiring emergency surgery to prevent complications and preserve fertility.

## Contribution

Highlights a rare clinical scenario of bilateral giant asymptomatic endometriotic cysts with unilateral rupture and emphasizes the importance of rapid surgical intervention.

## Key findings

- Emergency surgery revealed a ruptured right ovarian cyst and a left ovarian cyst in a 25-year-old woman.
- Histopathology confirmed both cysts were endometriotic.
- Surgical intervention and hormonal therapy are recommended to prevent adhesion formation and recurrence.

## Abstract

Endometriotic cysts are common, but bilateral giant endometriosis cyst with asymptomatic cases are extremely rare. Rupture is also uncommon, yet when it occurs, it can mimic appendicitis or ectopic pregnancy due to peritoneal irritation, often requiring emergency intervention. A 25-year-old woman presented with nausea, vomiting, and an enlarging abdominal lump. Ultrasonography revealed bilateral ovarian cystic masses with ground glass appearances and free subhepatic fluid. Due to worsening symptoms despite initial resuscitation, emergency exploratory laparotomy was performed. Intraoperatively, a ruptured right ovarian cyst (20 × 15 × 15 cm) with extensive adhesions to the posterior uterus, rectum, and right ovarian fossa was identified, along with a left ovarian endometriotic cyst (12 × 10 × 10 cm). The patient underwent right salpingo-oophorectomy, left cystectomy, and ureterolysis. Histopathology confirmed endometriotic cysts. Rapid surgical intervention is crucial in ruptured cysts to minimize adhesion formation and preserve fertility. Postoperatively, continuous hormonal therapy, such as oral progesterone or an intrauterine device, is recommended to decrease recurrence.
