Takotsubo cardiomyopathy due to a pheochromocytoma: a case report.

Takotsubo cardiomyopathy is typically triggered by severe adrenergic surges secondary to various stress factors. In rare cases, excessive catecholamine secretion due to a pheochromocytoma may be the cause. It is typically manifested by dyskinesia of the apex of the left ventricle. In this case report, we describe an atypical case of takotsubo cardiomyopathy, characterized by hypokinesia of the apical and mid-segments of the inferior wall of the left ventricle, which led to the discovery of an underlying pheochromocytoma. Although this association is rare, it is crucial to consider it, especially in atypical forms, as once the tumor is resected, the phenomenon becomes reversible.
