Multi-modality imaging of pheochromocytoma

Pheochromocytoma, a rare neuroendocrine adrenal tumor, is often diagnosed by a combination of clinical, laboratory, and radiographic features. While the imaging features of this entity are variable, the use of complementary modalities often helps to target the diagnosis and assess the extent of the disease. We present a multi-modality evaluation of a pheochromocytoma, with CT, MR, MIBG, and pathologic findings, in an individual who initially presented to the Emergency Department with flank pain.
