MRI findings in adrenal pheochromocytomas. (A) Sagittal MRI demonstrates a mass (arrow) displacing the inferior vena cava anteriorly (arrowhead). This caval displacement is typically seen with tumors arising in the adrenal gland. (B) Coronal MRI of the abdomen demonstrates a large mass in the right adrenal bed (arrow), lying immediately superior to the kidney. The low signal intensity in the center is caused by hemorrhage into the tumor.
