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

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.
