Radiographic manifestations of cardiac sarcoid

On the basis of autopsy series, the incidence of direct cardiac involvement in sarcoidosis has been estimated to be 20%-27%. It may be recognized clinically when patients with known systemic sarcoidosis present with arrhythmias, conduction disturbances, or cardiomyopathy. Various radiographic manifestations of cardiac sarcoid, including cardiomegaly, pericardial effusion, and left ventricular aneurysm, are described in four patients.
