Abstract

Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are both rheumatological diseases of the elderly with a strong association with each other and which rarely present with normal inflammatory markers. Here we present the case of a 61-year-old Caucasian woman who had typical symptoms of both diseases. At the time of presentation, her blood work showed normal inflammatory markers, but because of the high clinical suspicion for GCA, a temporal artery biopsy was done which was positive for giant cells and disruption of the internal elastic lamina. Our patient responded very well to treatment with oral steroids and steroid-sparing medication and was able to return to her normal life without experiencing any complications of the disease. By sharing our case, we aim to increase the awareness of medical personnel regarding the importance of focusing on the clinical presentation as well as the laboratory and pathological aspects of diagnosing GCA and PMR.
