Heart combined with adrenal multiple pheochromocytomas.

Pheochromocytoma is a kind of rare tumor, occurring at any site in the sympathoadrenal system. Main lesions occur within the adrenal gland; only 1%-2% occur within the chest, and most of these are located in the posterior mediastinum. Intrapericardial pheochromocytoma is extremely rare in clinic, only about 100 cases have been reported in total in both the domestic and foreignliterature since Besterman et al. first reported in 1974. It is often difficult to diagnose and locate these tumors. Hence, we present here a case of adrenal combined with heart multiple pheochromocytomas and discuss about techniques contributed to diagnosis and localization.
