# Ovarian Torsion Secondary to a Mature Cystic Teratoma in a Four-Year-Old Girl: A Case Report

## TL;DR

A four-year-old girl was diagnosed with a benign ovarian tumor that caused abdominal pain and required surgery.

## Contribution

This case report highlights adnexal torsion as a complication of mature ovarian teratoma in a young pediatric patient.

## Key findings

- A four-year-old girl presented with acute abdominal pain due to ovarian torsion from a mature cystic teratoma.
- Surgical intervention confirmed the diagnosis of a benign mature ovarian teratoma.
- Ultrasound imaging showed a vascularized spiral mass, aiding in preoperative diagnosis.

## Abstract

Teratomas are the most common histological subtype of germ cell tumors in pediatric patients. They are classified into two types: mature(benign) and immature(malignant). Early diagnosis is essential for optimal management. Adnexal torsion is the most frequent complication of mature ovarian teratoma, with a higher incidence in young girls. We report a case of a four-year-old girl who arrived at the emergency department with acute left flank abdominal pain and non-bloody vomiting, 24 hours prior to admission. Abdominal ultrasound revealed a large cystic abdominal mass with a Doppler-detected vascularized spiral configuration. Surgical management was performed via a Pfannenstiel laparotomy, which revealed a mature ovarian teratoma.
