Mammary intra-arterial calcification (MIAC) was seen on the mammograms of 13 of 150 (8.7%) known diabetic patients and 21 of 300 (7.0%) age-matched control patients. Statistical analysis verified no significant difference between the rate of occurrence of MIAC in the diabetic group of patients and the control group. Therefore, contrary to previous reported studies, our study does not support the conclusion of an increased frequency of MIAC in diabetic patients. MIAC is a manifestation of peripheral vascular disease resulting from a variety of causes, one of which may be diabetes.
