Pseudotumour cerebri syndrome: case report An 18-year-old man received oral levofloxacin 500mg (two capsules daily) for broncho-pneumonia which was unresolved after 7 days of amoxicillin treatment. He developed tinnitus in his left ear, blurred vision, photophobia, headache and intermittent horizontal diplopia and vomiting 5 days later. His visual acuity was 9/10 in both eyes and ocular motility exam revealed palsy of his left VI cranial nerve. Marked bilateral papilloedema with some flame-shaped haemorrhages were seen during fundus oculi examination. Perimetry indicated enlargement of his blind spot. Lumbar puncture revealed raised opening pressure of 41cm of CSF. Levofloxacin was withdrawn 2 days after lumbar puncture. His symptoms resolved completely 2 weeks later. Author comment: "[T]he quick resolution of the headache, blurry vision, papilloedema, and diplopia after stopping levofloxacin intake supports a causal relationship between this antibiotic and intracranial hypertension, although a beneficial effect of the lumbar puncture cannot be ruled out."
