To briefly review the most commonly used non-surgical treatments of hepatocellular carcinoma To show the varying appearance of both recently and remotely treated lesions To illustrate imaging features suggestive of recurrent tumor versus post-treatment change  

Review of commonly performed treatments for primary liver malignancies Transarterial interventions: chemoembolization (TACE), bland embolization Thermal treatment: radiofrequency ablation, cryoablation, microwave ablation Case based Radiology-Pathology correlation of treated hepatic lesions TACE Imaging appearance of embolic material at treatment site Appearance of fibrous capsule surrounding treatment site Post-treatment vascular shunts and venous thrombosis that mimic recurrence Thermal ablation Hypodensity and surrounding contrast enhancement patterns at CT T1 and T2 signal characteristics and enhancement characteristics at dynamic MR Case based Radiology-Pathology correlation of residual and recurrent disease TACE Disappearance of embolic material over time, as related to revascularization and recurrence Nodular enhancement at CT/MR consistent with recurrence Thermal ablation Examples of nodular enhancement around treatment site that suggest recurrence
