Not all that thickens is hypertrophic cardiomyopathy: a case report of unusual Takotsubo cardiomyopathy

This case underscores the diagnostic complexity at the intersection of TTC, myocardial infarction with non-obstructive coronary arteries, and HCM mimics. Cardiac magnetic resonance was pivotal in revealing myocardial oedema and excluding infarction or fibrosis. Reversible wall thickening in TTC may resemble apical HCM, a phenomenon termed pseudohypertrophy. Takotsubo cardiomyopathy should remain a key differential despite angiographic findings. Early multimodal imaging is crucial for avoiding misdiagnosis and guiding appropriate management.
