Abstract 한글 요약
[BACKGROUND] As the use of immune checkpoint inhibitors becomes more prevalent in cancer treatment, physicians should be aware of immune-related adverse events. Cardiovascular toxicity is of particular concern because of the risk of serious consequences, yet little is known about these immune-related adverse events including giant cell arteritis (GCA).
[CASE SUMMARY] A 68-year-old man complained of new-onset daily persistent headache and fever after pembrolizumab initiation for renal cell carcinoma. The patient was negative for vasculitis-associated autoantibodies and showed no significant findings on ultrasound or contrast-enhanced computed tomography. However, contrast-enhanced magnetic resonance imaging revealed gadolinium enhancement in both temporal arteries, and temporal artery biopsy showed findings consistent with GCA. Prednisolone was initiated immediately and dramatically improved the clinical symptoms, which prevented vision loss.
[CONCLUSIONS] This case highlights the importance of considering GCA as a possible diagnosis in patients receiving immune checkpoint inhibitors therapy who report development of new headache.
