It is difficult, but important, to diagnose extra-adrenal pheochromocytomas before surgery. Failure to recognize the existence and nature of an extra-adrenal pheochromocytoma can cause life-threatening problems even in a minor surgical operation. We present two rare cases of extra-adrenal pheochromocytomas which were detected by 131I-MIBG scintigraphy. One of them was intrapericardial, and the other was a vesical pheochromocytoma. We used a combined 99mTc-MDP bone scan and 131I-MIBG scintigraphy to locate the pheochromocytomas. Both cases of extra-adrenal pheochromocytoma were correctly diagnosed preoperatively and successfully resected in the subsequent operations.
