The early clinical symptoms of Takayasu arteritis (TAK) are nonspecific and often lead to misdiagnosis or delay in diagnosis. And by the time morphological changes are observed on the images, the disease is in an advanced stage and irreversible vascular injuries has occurred. Therefore, early correct diagnosis and timely systemic anti-inflammatory treatment can effectively improve the clinical situation. Conventional imaging provides only changes in vascular structure and provides little information on inflammatory activity. Here we report the PET/CT imaging presentation of 18F-deoxyglucose (18F-FDG) in a patient with TAK, a 58-year-old patient with known TAK whose disease clustered many non-specific features, and highlight the value of PET/CT in the diagnosis and management of patients with early or atypical clinical presentation of TAK.
