A Case of Bilateral Pheochromocytoma : Findings of US, CT, MRI and 131I-MIBG Scan

Pheochromocytoma occurs at all ages but is most common in young to mid adult life. In adults 10 percent of pheochromocytoma are bilateral. And bilateral lesions are common in the familial syndromes; within Multiple Endocrine Neoplasia (MEN) kind reds over half with pheochromocytomas have bilateral lesions. We report a case of bilateral pheochromocytoma firstly detected by ultrasonogram. This 24-year-old male was normotensive and had symptoms of dilated cardiomyopathy and elevated VMA level. CT and MRI were performed to evaluate the tissue nature and associated abnormalities. 131I-MIBG scan seems to be the imaging of choice in patients with suspected multi centric/bilateral or recurrent or metastatic pheochromocytomas.
