Catecholamine-secreting paraganglioma. The problem of classification.

Sudden catecholamine release, associated congestive heart failure, acute injury changes on ECG, and elevation of cardiac enzyme levels were observed after biopsy of a mediastinal mass. Five months later, a normal ECG and coronary arteriogram were recorded. Initial severe avoid unexpected catecholamine release, we recommend that all paragangliomas be evaluated for catecholaime production.
