Monckeberg's arteriosclerosis

Monckeberg's arteriosclerosis, also called medial calcific sclerosis, is calcific sclerosis of the media of medium-sized arteries. This type of arteriosclerosis neither affects the intima nor diameter of the luminal vessel, thus it does not limit arterial flow. It is more frequent in people over 50 years of age.

It is not related to other types of arteriosclerosis. On blood pressure reading, the systolic pressure is usually the only one elevated, and the diastolic pressure is close to normal, which gives the characterisitic "wide" pulse pressure.
