CTICasesConstrictive Pericarditis with Circumferential Pericardial Calcification
Imaging findings
Imaging shows bilateral pleural calcification along with circumferential, diffusely thickened and calcified pericardium in a patient who underwent pericardial stripping for constrictive pericarditis; the calcification spares the cardiac apex and shows a focal deposit in the right AV groove.
Key takeaways
Diffuse, circumferential pericardial calcification with sparing of the cardiac apex and a right AV groove deposit is a recognized pattern of chronic inflammatory (rather than asbestos-related) constrictive pericarditis -- apical sparing is thought to reflect relative protection from the greater cardiac motion at the apex -- and this pattern should be favored over an asbestos-related etiology even when co-existing pleural plaques suggest asbestos exposure.
