Abstract

A 60-year-old woman with a history of malignant lymphoma was referred to us with fever, sore throat, right-sided neck pain, and swelling while she was currently undergoing chemotherapy. Imaging studies, including computed tomography and ultrasonography of the neck, revealed significant perivascular wall thickening of the right carotid artery, which was suggestive of giant cell arteritis. However, fever, neck pain, and swelling resolved spontaneously and rapidly. Transient perivascular inflammation of the carotid artery (TIPIC) syndrome was most likely. However, these symptoms developed shortly after the administration of granulocyte colony-stimulating factor (G-CSF). Accordingly, the patient was diagnosed with G-CSF-induced aortitis mimicking TIPIC syndrome.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
