[Intraorbital dermoid cyst. Apropos of a case].
Orbital dermoid cyst represents 3 to 4% of all primary orbital tumours. The intraorbital location is relatively rare. We report the case of a 9 year-old male child with an orbital dermoid cyst, who presented with progressive right proptosis, which had developed 3 months earlier. Visual acuity, ocular motility and funduscopic examination were normal. Imaging aspects (ultrasonography and computed tomography) have revealed an extraconical orbital, hypodense, well limited tumor, without bone destruction and no enhancement located at the postero-external side of the orbit. The tumors was extirpated surgically via a superior approach. Histopathology confirmed the diagnosis of dermoid cyst.
