Fever as the Sole Presentation of Giant Cell Arteritis: A Near Miss

Abstract

Giant cell arteritis (GCA) presenting solely as fever is very rare. Usually, it manifests with typical features such as visual problems, headache, jaw claudication, or it can be associated with polymyalgia rheumatica. We present a case of a patient with GCA who presented only with prolonged fever. The cause of fever could not be initially identified in spite of a comprehensive workup. The patient was started on steroids for presumed GCA resulting in the resolution of fever. It is of paramount importance to consider GCA in the differential diagnosis of fever of unknown origin. Early diagnosis with effective treatment is crucial since the mortality rate remains high for untreated cases.
