[Rare association of subperiosteal hematoma of the orbit with frontal extradural hematoma: a case report]. / Association rare d'un hématome sous-périosté de l'orbite et d'un hématome extradural frontal: à propos d'un cas.

Subperiosteal haematoma of the orbit associated with frontal extradural hematoma is very rare. We here report a case treated in our Department with a literature review. The study involved a 15-year-old boy, victim of head injury from white weapon, a week before his admission to the emergency room. He had inflammatory and painful exophthalmos on the left side, associated with left ophthalmoplegia and blindness. Brain scanner showed left frontal extradural hematoma associated with subperiosteal hematoma of the ipsilateral orbit. Frontal craniotomy associated with fracture orbitotomy allowed evacuation of the extradural hematoma, and then, of the subperiosteal hematoma. Patient´s outcome was favorable. Simultaneous occurrence of frontal extradural hematoma and subperiosteal hematoma of the orbit is extremely rare. Generally, attention is drawn by exophthalmos and visual disturbances. Emergency brain scan without contrast agent injection can be used to make a diagnosis. Prognosis depends on visual function, then adequate management helps to safeguard the eye and vision.
