Septic cavernous sinus thrombosis complicated by narrowing of the internal carotid artery, subarachnoid abscess and multiple pulmonary septic emboli.

A 56-year-old woman was admitted because of a high fever, right ptosis, chemosis, proptosis and ocular muscle palsy. Cranial MRI revealed a cavernous sinus thrombosis and a subarachnoid abscess. Carotid angio-gram demonstrated marked stenosis as well as aneurismal formation of the right internal carotid artery at the intracavernous portion. Chest radiograph showed bilateral multiple pulmonary nodules, some of which contained a cavity. Blood culture was positive for Streptococcus constellatus. She was diagnosed with septic cavernous sinus thrombosis complicated by narrowing of the internal carotid artery, subarachnoid abscess and multiple pulmonary septic emboli. She recovered with partial ocular sequelae as a result of seven weeks of intravenous antimicrobial therapy.
