We present the case of two patients with extra-adrenal pheochromocytoma (left and right para-aorta abdominal) in which the pre-surgery search with metaiodobenzylguanidine-I-123 (MIBG-I-123) showed the existence of bone metastasis in skullcap, not previously suspected. In both patients a total resection of tumor was performed together with the bone lesions. These two cases confirm the great usefulness of MIBG-I-123 in the localization of metastasis in patients with malignant pheochromocytoma. At the same time we think that the resection of whole tumoral tissue through surgery is an adequate treatment when dealing with pheochromocytoma with isolated metastasis.
