Abstract:

Objective To investigate the sonographic and CT features of hepatic masses caused by liver involvement in hematological

malignancies in order to improve diagnostic acurracy. Methods From April 2012 to May 2015，16 patients with hepatic masses caused by liver involvement in hematologic malignancies were respectively analyzed. Hepatic masses were present in patients with non-Hodgkin's lymphoma（9／16），Hodgkin's disease（2／16），multiple myloma（1／16），acute myeloblastic leukemia（2／16），acute lymphocytic leukemia（1／16）and chronic lymphocytic leukemia（1／16）. Results The most frequent sonographic appearance was multiple small focal lesions，and less frequent appearance was single lesions. Most lesions showed regular round，round like or oval shapes，while few lesions showed irregular shapes. The hypoechoic lesions were found in 13 cases，while mixechoic and hyperechoic lesions were found in 1 and 2 cases，respectively. Poor or no color flow signal was found in the lesions.Unenhanced CT showed that multiple focal hypoattenuating lesions were in most cases.Enhanced CT showed no evident enhancement or slight enhancement. More lesions were found in right hepatic lobes than in left lobes. The sonographic and CT features of hepatic masses caused by liver involvement in hematological malignancies，including non-Hodgkin's lymphoma，Hodgkin's disease，multiple myloma，acute and chronic leukemia，are similar. Conclusion Ultrasound and CT show certain featrures in hepatic masses caused by liver involvement in hematological malignancies. The combination of ultrasound and CT is preferred as non-invasive imaging diagnostic method.
