Headache, palsy, and an elevated ESR: not necessarily giant cell arteritis.
Elderly people often have cranial nerve (CN) palsies. Most cases are ischemic and self-limited.[1][1] Diplopia and an elevated erythrocyte sedimentation rate (ESR) are sometimes observed in giant cell arteritis (GCA).[2][2] The incidence of diplopia among people with GCA is estimated at 10% to 17%.
