Spontaneous subperiosteal hematoma of the orbit

Spontaneous subperiosteal hematoma of the orbit is extremely rare. This is a case of an 81-year-old woman. The presenting symptom was protrusion of the right eye with severe intraorbital pain. Computed tomography scanning showed a high-density area in the upper part of the right orbit, which, at operation, was found to be a subperiosteal hematoma of the orbit.
