Ophthalmoplegia resulting from an intraorbital hematoma.

Background: A case is described in which an intraorbital hematoma was found to complicate recovery from attempted aneurysm clipping 5 days into the postoperative period. The etiology, management, and complication avoidance are discussed.
Case Description: Five days after attempted surgical clipping of an internal carotid artery aneurysm via a frontotemporal craniotomy with orbital osteotomy, a patient underwent coiling of the aneurysm. Shortly after the endovascular procedure, the patient developed exophthalmos and ophthalmoplegia involving the right side followed by decline in her level of consciousness. An emergency computed tomography (CT) scan revealed an epidural hematoma with intraorbital extension. After evacuation of the hematoma, the patient recovered extraocular function and returned to her baseline mental status.
Conclusion: Exophthalmos and ophthalmoplegia in a patient recovering from cranial surgery using skull base techniques warrants immediate attention, especially after endovascular procedures. Delay in intervention may result in loss of neurologic function or life. The authors discuss the relevant literature and management of this uncommon complication.
