Rapid Onset Development of Myocardial Calcifications in the Setting of Renal Failure and Sepsis.

Myocardial calcifications can arise following damage to myocardial tissue or in the setting of disturbances in the calcium and phosphorus balance. They are associated with a number of cardiac sequelae, as well as higher mortality. Three cases of rapid-onset myocardial calcifications that developed within the course of 5 to 13 weeks in patients who had a history of sepsis and renal failure while undergoing hemodialysis are described. Baseline imaging from several weeks prior without myocardial calcification are shown for each of the three patients, demonstrating the rapid onset of these calcifications. The clinical significance of these findings is discussed. © RSNA, 2021. 2021 by the Radiological Society of North America, Inc.
