Abstract
Giant cell arteritis (GCA), also known as temporal arteritis (TA), is a systemic autoimmune inflammation of medium and large arteries. It is the most common vasculitis affecting adults older than 50, with an incidence of 20/100,000 and an average age of onset of 70. Typically, patients initially present with new-onset headaches, visual changes and disturbances, jaw claudication, arthralgias, and tender or swollen temporal or occipital arteries. Our patient is a 73-year-old male who presented to the emergency room with 10 days of bilateral headache radiating to the occipital area associated with fevers, persistent chills, generalized weakness, and a headache described as constant, dull, 9 out of 10 pain, and minor pain with neck flexion. Lab work revealed an elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The patient had tender palpation to his temples and due to a high suspicion of giant cell arteritis, he was started on high-dose steroids with rapid relief of his symptoms. Biopsy showed evidence of active non-granulomatous vasculitis and confirmed bilateral temporal arteritis within the context of the clinical setting. GCA patients are more likely to be women and typically present with unilateral headache (66% of GCA), jaw claudication (50%), fevers (50%), and transient visual loss (16-54%). Here, we describe a 73-year-old male with a past medical history of cerebral vascular accident (CVA), diabetes, and cancer that presented with 10 days of bilateral headaches and fevers. Unlike the usual presentation, our patient denied any vision and joint pain changes, and the temporal arteries were not stiff to palpation. This patient presentation is unique to previous reports in the limited display of symptoms and absence of the most commonly associated manifestations. Although his presentation supported GCA, the features of elevated ESR and CRP, headache, and fever were too general to diagnose GCA exclusively, and his additional symptoms of rhinorrhea and sinus pain more likely supported infection. Our case indicates the importance of maintaining a high index of clinical suspicion for GCA in the elderly population presenting with headaches and elevated ESR and CRP. GCA, also known as temporal arteritis (TA), is a systemic autoimmune inflammation of medium and large arteries. Typically, patients initially present with new-onset headaches, visual changes and disturbances, jaw claudication, arthralgias, and tender or swollen temporal or occipital arteries. Diagnosis requires high clinical suspicion, and treatment revolves around high doses of steroids.
