The cause of nephrocalcinosis in systemic granulomatous disease is:
Overproduction of 1,25 dihydroxy vitamin D
Dystrophic calcification
Mutation in calcium sensing receptors
Increased reabsorption of calcium
Nephrocalcinosis is deﬁned as calciﬁcation of the renal interstitium and tubules. It is associated with hypercalcemia, which occurs due to overproduction of vitamin D.
