Pheochromocytoma-Induced Acute Myocarditis
نویسندگان
چکیده
Pheochromocytoma is a neuroendocrine tumor, characterized by an excess of catecholamine production, which results in paroxysmal or sustained hypertension, even hypertensive crisis. The classic triad of pheochromocytoma is paroxysmal headache, sweating and palpitation. Myocarditis is a rare manifestation of pheochromocytoma. We report 2 middle-aged women with a long history of hypertension and headache, presenting initial symptoms mimicking acute coronary syndrome and finally developing heart failure and unstable hemodynamics. The characteristic fluctuation of blood pressure and hypertensive crisis prompted us to further survey and diagnose this rare pheochromocytoma-related myocarditis.

Pheochromocytoma is a rare tumor, usually benign, potentially lethal in case of crisis with acute release of catecholamines. The heart is a target and the clinical presentation can mimic various cardiac conditions, thus rendering diagnosis elusive. Cardiac magnetic resonance is a valuable non-invasive diagnostic tool for the evaluation of cardiomyopathies; it allows the identification of catech...
متن کاملAdrenergic Myocarditis in Pheochromocytoma
The clinical presentation of pheochromocytoma is variable and many biochemical and imaging methods have been suggested to improve the diagnostic accuracy of what has been termed "the great masquerader". This case-report is of a middle-aged woman with a non-specific clinical presentation suggesting acute coronary syndrome or subacute myocarditis. Cardiovascular magnetic resonance (CMR) at presen...
متن کاملPheochromocytoma Presenting with Multiple Cardiovascular Manifestations
Excess concentrations of catecholamines in pheochromocytoma can cause various clinical manifestations. There are few reports of pheochromocytoma presented with stress-induced cardiomyopathy (catecholamine-induced cardiomyopathy) after mild stress and the case of pheochromocytoma associated with nonocclusive stroke is more uncommon. We report a case of pheochromocytoma manifested repeated stress...
متن کاملCardiomyopathies: The Value of Cardiac Magnetic Resonance Imaging
Pheochromocytoma is rare and has been documented to present atypically as myocardial ischemia, arrhythmias, or congestive heart failure. In patients with pheochromocytoma, transient cardiomyopathy with hypokinesia of the basal segments of the left ventricle and hyperkinesia of the apex (an inverted Takotsubo contractile pattern) can be observed [5] . Patients with elevated cardiac biomarkers an...
متن کاملMagnesium sulphate and (123)I-MIBG in pheochromocytoma: Two useful techniques for a complicated disease.
Pheochromocytoma is a tumour of the chromaffin tissue. It may, through catecholamine release, have deleterious effects on myocardial structure. A 48-year-old woman with a history of hypertension and type II diabetes mellitus (ASA II) was diagnosed of pheochromocytoma-induced myocarditis, which caused severe cardiogenic shock, with an ejection fraction of 20%. Extreme blood pressure swings requi...
