Here, we report a rare case of isolated leukemic infiltrate of the myocardium (extramedullary involvement) presenting as restrictive cardiomyopathy in a patient in complete remission of acute myeloid leukemia. It was evaluated with multimodality imaging studies (echocardiography and cardiac MRI) and further confirmed by pathology. The present case highlights the importance of maintaining a high degree of clinical suspicion when evaluating patients with progressive ventricular hypertrophy of unknown cause, including recognition of the potential involvement by recurrent hematologic malignancy.
