Abstract: Takayasu arteritis is a chronic vasculitis involving the large vessels. At diagnosis, ischemic symptom are usually present in the affected vessels. However, fever of unknown origin (FUO) is rare as an initial presentation and renders the condition difficult to diagnose. In this case report, we describe a patient who presented with a fever of unknown origin. A 68-year-old female was diagnosed with Takayasu arteritis after fluorodeoxyglucose (FDG) positron-emission tomography-computed tomography (PET-CT) was performed at the prepulseless stage. FDG PET-CT can assist in the early diagnosis of Takayasu arteritis patients with FUO and can improve the prognosis of such patients.
