Puncture injection of para-toluenesulfonamide combined with chemoembolization for advanced hepatocellular carcinoma

Figure 1 Transcatheter arterial chemoembolization had little effect on the hepatocellular carcinoma, but restrict the size of tumor mass. A: Contrast computer tomography (CT) before the procedure showed a huge hypodense mass with remarkable enhancement and portal vein embolus; B: Two months after the initial 2 series of transcatheter arterial chemoembolization, contrast CT still found a hypodense nodule with partial contrast enhancement and portal vein invasion.
