Mönckeberg calcification in a temporal artery

Mönckeberg’s calcification is a disease of low prevalence and unknown etiology that causes calcification of the middle layer of medium and small arteries. It usually presents with a clinical picture similar to giant cell arteritis, so a differential diagnosis with similar entities should be made. The diagnosis is anatomopathological, and there is no treatment that has shown significant results. Herein, we present the case of a 74-year-old male patient with recurrent syncope and chest pain, in whom giant cell arteritis was suspected and a temporal artery biopsy was taken with the incidental finding of calcification of Mönckeberg’s media.
