CTICasesPericardial Plaque (Asbestos-Related)
Imaging findings
CT submitted for consultation shows discrete calcified plaque-like thickening involving the pericardium itself, away from the pleural surface and present bilaterally along the mediastinal contour, in a patient with known asbestos-related pleural plaques elsewhere; the remainder of the pericardium appears normal without diffuse calcification to suggest constrictive calcific pericarditis.
Key takeaways
This is an unusual and rarely documented example of a true pericardial plaque, distinct from the far more common medial pleural plaque that is often loosely described as pericardial plaque, occurring in a patient with documented asbestos exposure and pleural plaque disease elsewhere; the discrete, localized, non-diffuse pattern of calcification argues against calcific pericarditis and instead supports a plaque-like asbestos-related process directly involving the pericardium.
