A 67-year-old woman presented to the ED of a tertiary hospital with sudden onset of difficulty expressing words, associated with a frontal headache. She reported general malaise, muscle weakness, and a persistent abnormal sensation in her legs in the preceding couple of weeks. These symptoms presented on a background of refractory asthma, which had been diagnosed in early childhood. She had been on maintenance therapy of 10 mg prednisolone daily (which she titrated based on her exacerbations), in addition to fluticasone/salmeterol 250 μg/50 μg metered-dose inhaler, two puffs bid. There was no history of rhinosinusitis or nasal polyposis. Two years prior, she had an episode of amaurosis fugax, which was treated as temporal arteritis (no histology was undertaken), with oral steroids.
