Orbital cellulitis and cavernous sinus thrombosis secondary to necrobacillosis.

摘要

Necrobacillosis, the septicaemic disease caused by Fusobacterium necrophorum, is a rare and potentially fatal disease. The original description of Lemierre included fever, rigors, arthritis, and pulmonary infarct occurring after an episode of sore throat. The mortality and morbidity is commonly due to thrombotic complications and septicaemia. We report a case of F. necrophorum septicaemia causing orbital cellulitis and cavernous sinus thrombosis in a healthy young female patient.Case report A 23-year-old female patient was admitted to the infection unit with high fever (40degC) left facial swelling, right proptosis, diplopia, and decreased vision for 2 days. She had been treated with clarithromycin for a sore throat 3 weeks before presentation. Examination revealed visual acuity of 6/24 on the right and 6/5 on the left, proptosis (26 mm OD, 22 mm OS), conjunctival chemosis, and painful limitation of gaze.
