A 17-year-old young woman presented to Patan Hospital, Kathmandu, Nepal, with high-grade fever and headache for 4 days and non-projectile vomiting for 1 day. She also had blurred vision with dizziness on and off. There was no abnormal physical finding. Enteric fever was suspected, and she was empirically started on azithromycin (20 mg/kg) for 7 days. She became afebrile after 2 days and was followed up in 7 days with diplopia since 5 days. At this time, the blood culture was positive for Salmonella serovar typhi. On examination, there was isolated left lateral rectus palsy which accounted for her diplopia. Methylprednisolone (1 mg/kg) was prescribed which was tapered over 1 month and gradually her diplopia subsided. We hypothesise that vasculitic change in the blood vessel supplying the left abducens nerve could be causing the diplopia.
