Contrast-enhanced US with Sonazoid showed the same sites enhanced in the vascular phase, and showed contrast defect in the postvascular phase. Plain CT showed low density tumors with unclear boundary. In dynamic CT, arterial phase showed the tumors enhanced faintly, and portal-venous phase showed low density tumors compared with surrounding liver. Gd-EOB-MRI showed multiple tumors which were enhanced in arterial phase, and showed low intensity in hepatocyte phase. Portal vein was observed in the S3 tumor. PET-CT showed multiple abnormal accumulation in the liver, mediastinal lymph node, and hilar lymph node. We underwent a liver tumor biopsy because the tumors were atypical as HCC, and showed an elevation of IL-2R. Biopsy histology showed the finding of MALT lymphoma. Thus we underwent chemotherapy. This case is a valuable case because multiple lesions of hepatic MALT lymphoma with type C cirrhosis is rare, and chemotherapy has become possible after diagnosis by tumor biopsy.
