Primary hepatic lymphoma: ultrasound and pathology / 中华超声影像学杂志

ABSTRACT

Objective To investigate the relationship between ultrasound features and pathological types of primary hepatic lymphoma (PHL).Methods Ultrasound and pathological features in 26 cases of PHL were analyzed retrospectively.Results The most common presentation of PHL was a solitary lesion,which occurred in about 57.7％ (15/26) of cases,followed by multiple lesions in about 26.9％ (7/26) of patients,and least commonly as diffuse infiltration patterns in about 15.4％ (4/26) cases.The first two types were similar and usually demonstrated as hypoechoic lesions to the surrounding normal liver parenchyma in 86.4％ (19/22) of cases on ultrasound.All the cases were B-cell non-Hodgkin lymphoma proven by histological and immunohistochemical examinations.The diffuse pattern demonstrated diffuse hepatomegaly without nodular,which were T-cell non-Hodgkin lymphoma proven by histological and immunohistochemical examinations.Conclusions PHL could be divided into single,multiple and diffuse types on ultrasound.The single and multiple types mainly present as hypoechoic lesions and the diffuse type shows hepatomegaly on ultrasound,which are closely related to histology and T or B-cell phenotype on immunohistochemical examination.
