Diagnosis of Focal Nodular Hyperplasia (FNH) after Liver Transplantation

Figure 3

Retrospective review of a contrast-enhanced CT of the liver performed 8 months prior to contrast-enhanced MRI demonstrates portal vein thrombosis (dotted arrow) and a 2.3-cm lesion in segment 7 (arrow) that is faintly hypodense on precontrast (a), enhances centrally with a hypoenhancing rim on arterial phase (b), and subtly hypodense with a subtle rim of hyperenhancement on 3 min delay phase (c). In a patient with chronic liver disease, this appearance would be suspicious for HCC.
