ABSTRACT
Patients with cirrhosis are high risk for developing hepatocellular carcinoma (HCC) and warrant surveillance using abdominal ultrasound and α-fetoprotein.1 Those with positive surveillance results should undergo diagnostic evaluation with multiphase computed tomography (CT) or magnetic resonance imaging (MRI). The LI-RADS system is an evidence-based system to classify observations on CT or MRI in at-risk patients, ranging from LR-1 (definite benign) to LR-5 (definite HCC), with LR-3 and LR-4 observations being intermediate risk for HCC.2 LR-3 and LR-4 observations are observed on CT or MRI in more than one-fourth of patients undergoing HCC surveillance and have a high, yet variable, risk for progression to HCC.3 Approximately one-third of patients with LR-3 observations and more than two-thirds of LR-4 observations develop HCC, and surveillance strategies vary widely in practice.4,5 Variation in radiographic appearance and natural history of these observations suggests that this may be a heterogeneous group of patients; however, their histopathology has not been well described. Herein, we correlated imaging findings and explant histopathology from liver transplant recipients with at least 1 LR-3 or LR-4 observation on CT or MRI within 6 months preceding transplantation.
