[Abstract] Purpose： To improve realization of CT and MRI characteristic in patients with hepatic lym- phoma. Materials and Methods： We reviewed 24 patients whose diagnosis of lymphoma was finally made histologically. In all patients, five of them were diagnosed Hodgkin＇s disease （HD） and 19 of them were diagnosed non- Hodgkin＇ s lymphoma （NHL） . Two cases were primary hepatic NHL （ one by op- eration and another by biopsy）. In other 22 cases, liver lesions were observed at the onset of the disease or during the follow - up period. Some liver lesions disappeared and others reduced after treatment, thus, we concluded liver was infiltrated by lymphoma. CT scans were performed in 21 patients, MRI examinations were performed in 8 patients. Results： ~ In all 24 cases, eight cases presented single liver lesion （33%）, 15 cases presented multiple lesions （63%）, only one case presented diffuse lesions（4% ）. （~） Unenhanced CT showed hypoattenuating lesions in most cases （13/14） ; Enhanced CT showed no evi- dent enhancement （11/21） or mild enhancement （10/21）. （~ On MR T~WI imaging, all lesions were pre- sented as hypointense, on MR T2WI imaging, most cases （6/8） showed hyperintense. After contrast ad- ministration, all lesions presented no evident enhancement （3/8） or mild enhancement （5/8）. （~） Blood vessel traverse lesions or lesions invade along the vessels and the vessels were not narrowed and encir- cled in 6 cases. Conclusion： In most cases, liver lymphoma represent hypoattenuation or hypointense, manifest clear margin, have no evident enhancement or mild enhancement after contrast administration. Blood vessel traversing lesions or lesions invading along the vessels without narrowing or encircling may be a characteristic sign. Combining imaging characteristic and clinical information, liver lymphoma can be identified correctly.
