MRI of primary lymphoma of the liver.
OBJECTIVE
The MR findings in two cases of primary lymphoma of the liver (PLL) are presented.


METHODS
MR of two cases of primary lymphoma of the liver were reviewed and its features were estimated.


RESULTS
Both cases showed a solitary large liver mass. On T1-weighted imaging the tumor was isointense in one and homogeneously hypointense to the liver parenchyma in the other. On T2-weighted imaging both tumors were homogeneously hyperintense. In one case the margin of the tumor was poorly defined, and portal branches were identified within the tumor, an unusual finding in other liver neoplasms.


CONCLUSIONS
In patients with liver masses with homogeneous intensity on MR but without liver dysfunction and other malignancies, PLL should be included in the differential diagnosis.
