Catecholamine-Induced Cardiomyopathy Initially Misdiagnosed as Myocarditis in a Patient With Pheochromocytoma

Key Result

Blood pressure lability in young patients with suspected myocarditis should prompt immediate biochemical screening for pheochromocytoma to identify catecholamine-induced cardiomyopathy.

Key Points

• This report aims to highlight the misdiagnosis of catecholamine-induced cardiomyopathy as myocarditis in the context of pheochromocytoma.
• Descriptive case report of a young patient with blood pressure lability and suspected myocarditis.
• Emphasis on biochemical screening for pheochromocytoma due to unusual symptoms.
• Patient initially misdiagnosed but later identified with catecholamine-induced cardiomyopathy.
• Blood pressure variations prompted further investigation leading to diagnosis of pheochromocytoma.
