Uptake of Ga-67 in the cardiac region in hypersensitivity angiitis

Although Ga-67 can be used to recognize various inflammations of the heart and pericardium, it is seldom used to evaluate the inflammatory process of a myocardial infarction because of lack of specificity, lack of early uptake, and other factors. However, inadvertent recognition on routine Ga-67 scans is always a possibility and has been reported once before. Here described is another case of silent, multiple myocardial infarction seen by Ga-67 scan as a consequence of multiple organ involvement with hypersensitivity angiitis. This incidental finding was the only indication of direct cardiac involvement at the time of the patient's death by cardiac arrest on the same day as the Da-67 scan.
