Abstract
We present two cases of hyperthyroid cardiomyopathy (CMP) caused by Graves’ disease in which multidetector computed tomography (MDCT) findings provided specific diagnostic clues, guiding the attending physician to a prompt diagnosis and allowing rapid initiation of therapy. We believe that a combination of diffuse thyroid enlargement, with decreased attenuation on non-enhanced chest CT, thymic hyperplasia and cardiomegaly (i.e. predominantly right heart failure with enlargement of the left atrium) are suspicious CT findings of hyperthyroid CMP.
