Calcium deposits in tunica media that have hardened into bone in a 50-year-old diabetic patient suggest which vascular condition?

• A. Monckeberg medial sclerosis
• B. Atherosclerosis
• C. Temporal arteritis
• D. Buerger disease

Answer: (A)

Calcium deposits that form in the tunica media and ossify into bone reflect Monckeberg medial sclerosis. This condition involves calcification of the muscular arterial wall (the media) with preservation of the intima, leading to stiff, noncompliant vessels rather than narrowing from lipid plaques. It commonly appears in older individuals and is associated with diabetes, which fits the clinical scenario. In contrast, atherosclerosis centers on the intima with lipid-rich plaques that encroach on the lumen and cause narrowing or occlusion, not ossified deposits in the media. Temporal arteritis is an inflammatory disease of large- and medium-sized arteries with granulomatous inflammation, not medial calcification. Buerger disease is a segmental inflammatory/thrombotic occlusive disease of small and medium arteries, typically in young smokers, and does not present with medial ossification.
