# When Exophthalmos Reveals an Orbital Dermoid Cyst in a Child: A Case Report

## TL;DR

A 10-year-old child's eye pain and bulging led to the discovery of a rare benign orbital dermoid cyst through imaging techniques like CT and MRI.

## Contribution

This case report highlights the importance of imaging in diagnosing rare orbital dermoid cysts in children.

## Key findings

- Eye pain and unilateral exophthalmos in a child revealed an orbital cystic lesion.
- CT and MRI imaging confirmed the lesion was consistent with an orbital dermoid cyst.

## Abstract

Orbital dermoid cysts are benign tumors most commonly found in young children. Although rare, their intraorbital location should not be overlooked. Imaging enables diagnosis and guides the surgical approach. We report the observation of an orbital dermoid cyst revealed by eye pain and unilateral exophthalmos of the left eye, in which imaging revealed an orbital cystic lesion whose radiological characteristics mainly suggest a dermoid cyst on computed tomography (CT) scan and magnetic resonance imaging (MRI). We report a case of an orbital dermoid cyst in a 10-year-old child.
