A case is presented in which chronic renal failure led to intense visceral calcification, mainly to the lungs and heart. The discovery of cardiac calcifications on plain chest radiographs is exceedingly rare in renal patients. Punctate calcific deposits with an almost homogeneous distribution throughout the cardiac muscle were the main feature of this case.

Some contrast media are able to release histamine from isolated mast cells of the rat and produce degranulation of these cells. Such properties are fairly correlated with the ability to increase vascular permeability in vivo and to produce a drop in blood pressure. If histamine is similarly being released in humans many untoward effects of these agents referred to clinically might be thus explained.
