Résumé
We highlight the dual role of I-MIBG scintigraphy in inverted-Takotsubo pattern cardiomyopathy, the diagnosis of which is sometimes challenging: Firstly, I-MIBG scintigraphy can show myocardial sympathetic dysfunction (low I-MIBG uptake) in the hypokinetic basal segments, sparing the left ventricle apex. It is helpful in the imaging diagnosis of inverted-Takotsubo pattern cardiomyopathy and confirms that acute dysfunction of myocardial sympathetic nerve endings occurs with this cardiomyopathy. Secondly, I-MIBG scintigraphy is an accurate imaging examination to detect and localize pheochromocytoma; it can help in the search for an endogenous cause of this adrenergic stress-related cardiomyopathy.
