Pheochromocytoma in a post-Fontan patient. A 24-year-old woman with previous hypoplastic right ventricle with dysplastic tricuspid valve. Axial CT images in the arterial (a) and portal venous (b) phases demonstrate a 4.5-cm heterogeneous enhancing mass originating from left adrenal gland (arrows). The patient underwent an operation and the lesion was confirmed as pheochromocytoma. Note numerous arterial enhancing foci with no delayed washout scattered in the liver in the arterial phase and heterogeneous poor parenchymal enhancement in the periphery of the liver in the portal venous phase (arrowheads). Caudate lobe is hypertrophied with relative homogeneous enhancement (asterisk)
