title: [A case of isolated hepatic malignant lymphoma representing characteristic findings on radiological imaging].
abstract: We present an 80-year-old-man who showed characteristic radiological findings of secondary hepatic malignant lymphoma. The patient was first admitted to our hospital 6 months before with left cervical mass, which was diagnosed as malignant lymphoma by biopsy. After complete response to chemotherapy, a large hepatic mass appeared, as the serum value of lactic dehydrogenase elevated. CT/MRI showed a well-demarcated hypovascular mass, which was penetrated by the right hepatic vein. The apparent diffusion coefficient of the mass was 0.70 x 10(-3) mm2/s. The patient was diagnosed as relapse of malignant lymphoma, mainly based on these radiological findings reflecting the mass with high cellularity which grows without destruction of existing vascular structure, and additional chemotherapy was given. The hepatic mass disappeared almost all and the serum value of lactic dehydrogenase decreased with in normal range. The patient was discharged in a good condition 2 months later.
