Takayasu Arteritis in a Middle-aged Woman Following Prolonged Subsequent Fever after COVID-19 Infection: An Early Diagnosis Using Contrast-enhanced CT.

A 59-year-old woman developed a persistent dry cough one month after recovering from coronavirus disease 2019 (COVID-19). She subsequently developed fever and back pain, and a local doctor diagnosed suspected infection and prescribed antibiotics. However, her symptoms did not improve and she was referred to our department. No definitive etiology was identified based on the initial physical examination, blood tests, and non-contrast computed tomography (CT). Her symptoms persisted for another week, and contrast-enhanced CT revealed aortic wall thickening. The patient was then diagnosed with Takayasu arteritis. As only a few cases of Takayasu arteritis have been reported after COVID-19, this case is valuable.
