  • Abstract
  • Look Inside

A 32-year-old woman was hit by a motorcycle while walking. She became comatous due to cerebral contusion. Magnetic resonance imaging(MRI)was performed on day 14 of injury. A crescent-shaped lesion,showing a niveau,was present in the supraorbital frontal bone. The finding was suggestive of subperiosteal hematoma of the orbit. She complained of diplopia when recovering from coma. When seen by us on day 19 of injury,her left eye showed restricted elevation and blepharoptosis. There was no abnormality in the visual field or acuity. The limited eye movement and diplopia spontaneously resolved on day 49 of injury,leaving moderate blepharoptosis. The niveau seen in the hematoma was probably due to degeneration of hemoglobin into methemoglobin and deoxyhemoglobin during 14 days after injury. The latter would have settled in the inferior portion of hematoma because of greater specific gravity.
