She was treated with corticosteroids and improved.

She was tapered off prednisone in late May and developed discomfort in her left ear with hearing loss and tinnitus.  Some left facial asymmetry was noted.

She was treated with intra-tympanic steroid injections as well as oral steroids with some improvement. Her last dose of corticosteroids was 3 weeks prior to being seen.

At the beginning of August she developed speech and swallowing difficulties and was neurologically diagnosed with palsies in 4th, 6th, 8th, 9th, 10th and 11th cranial nerves. Other symptoms included photophobia and a non-productive cough. Two additional LPs were reported to be normal.
