Correct Answer » D Explanation

Ans:D. Mönckeberg’s arteriosclerosis

MÖNCKEBERG’S ARTERIOSCLEROSIS (MEDIAL CALCIFIC SCLEROSIS)

• Mönckeberg’s arteriosclerosis is calcification of the media of large and medium-sized muscular arteries, especially of the extremities and of the genital tract, in persons past the age of 50.

• The condition occurs as an age-related degenerative process, and therefore, an example of dystrophic calcification.

• However, medial calcification also occurs in some pathological states like pseudoxanthoma elasticum and in idiopathic arterial calcification of infancy.

MORPHOLOGIC FEATURES.

• Medial calcification is often an incidental finding in X-rays of the affected sites having muscular arteries.

• The deposition of calcium salts in the media produces pipestem-like rigid tubes without causing narrowing of the lumen.

• Microscopically, Mönckeberg’s arteriosclerosis is characterised by deposits of calcium salts in the media without associated inflammatory reaction while the intima and the adventitia are spared.
