Comment: After the adrenal glands are scanned and if no mass is seen, scans through the rest of the abdomen are needed to rule out an ectopic pheochromocytoma. If IV contrast is used, pheochromocytomas are very vascular. In order to recognize an ectopic pheochromocytoma IV contrast in routinely needed. |
