Intracranial hemorrhage complicating an orbital decompression.

We report a case of intracerebral hemorrhage in the left frontal lobe following a left medial wall orbital decompression for thyroid-related optic neuropathy. There was no obvious fracture in the orbital roof bone but the hemorrhage was felt to occur from a disruption in the orbito-frontal branch of the anterior cerebral artery. The patient was asymptomatic and remained so during the follow-up period.
