title: Intracranial Infectious Aneurysm in Orbital Cellulitis.
abstract: Infectious intracranial aneurysm and cavernous sinus thrombosis are rare complications of orbital cellulitis. We report the case of a 46-year-old male presenting with sinusitis and orbital cellulitis complicated by the development of an orbital mass. Following orbitotomy with debulking, the patient underwent bony orbital decompression for increasing proptosis postoperatively. While his exam stabilized, the patient developed complete ptosis and extraocular motor palsy in the contralateral eye after undergoing bilateral sinus debridement. Imaging was notable for the presence of a pseudoaneurysm of the internal carotid artery, which was treated with a stent. This report demonstrates rare complications of orbital cellulitis. These patients should be monitored carefully with noninvasive imaging studies, such as cerebral angiography, for early detection of vascular abnormalities that can progress rapidly.
