Abstract

We report the radiological findings of regional enhancement of the liver adjacent to the right adrenal pheochromocytoma. CT and MRI showed focal strong enhancement of adjacent liver tissue in the arterial phase. However during the delayed phase, the lesion showed iso-attenuation with normal hepatic parenchyma and not delineated. The lesion did not show abnormal signal intensity on neither T1 nor T2 weighted images and indistinguishable from normal parenchyma. The enhancing hepatic lesion was spontaneously regressed on postoperative follow up CT which was taken several months after the adrenalectomy.

  Fig. 1 Pheochromocytoma in a 67-year-old Female Patient with Palpitation, Chest Pain and Nausea. a. Arterial (30S) phase CT shows a heterogeneously enhancing mass lesion in the right adrenal gland and a wedge-shaped enhancing lesion(arrows) in segment 7 of the liver. b. In delayed (180S) image, hepatic lesion (arrows) shows iso-attenuation. Five phase dynamic MR (c) precontrast, (d) 1 min, (e) 2 min, 3 min and 5 min(not shown) after contrast injection was performed. Lesion in segment 7 of the liver adjacent to the right adrenal mass presents strong enhancement (arrows) in 1 min delayed image and washes out afterwards. f. In a follow-up CT after adrenalectomy, wedge shaped enhancing lesion in S7 of the liver is spontaneously regressed and there is no demonstrable lesion in arterial (45S) phase CT .
