A case of pheochromocytoma complicated with acute renal failure and cardiomyopathy.

We encountered a case of pheochromocytoma which was characterized by the sudden onset of acute renal failure and pulmonary edema. Acute renal failure was rapidly improved after surgical removal of the tumor. This patient was also found to have a hypertrophied, dilated and hypokinetic left ventricle as assessed by echocardiography. Two years after tumor resection, cardiac size and function were normalized. This shows that a catecholamine-induced cardiomyopathy is reversible.
