Abstract
We present the case of a 46-year-old patient with hypothyroidism secondary to Hashimoto's thyroiditis who was admitted with decompensation in the form of myxedema. A 2-D echocardiogram shows a septal asymmetric hypertrophy, with low-voltage QRS complex in the ECG and a bull's-eye map of longitudinal strain with preserved apical strain with reduction of mid and basal strain that results in "cherry on the top" pattern, similar to the most frequent phenocopy of hypertrophic cardiomyopathy, as is the cardiac amyloidosis, and that, unlike this pathology, reverted after the patient reached the euthyroid state.
