Focal involvement of malignant lymphoma in the liver

In this study the sonographic findings of 30 patients with hepatic lymphoma have been reviewed. Lesions have been confirmed by autopsy (n = 1), laparatomy (n = 1), sonographically guided biopsy (n = 15), and during long-term follow-up (n = 13). Ten patients had Hodgkin's disease (HD) and 20 non-Hodgkin lymphomas (NHL). Focal lesions, less than 3 cm in diameter, were seen in 20 patients. The remaining ten cases presented large-nodule transformation of the parenchymal texture. All lesions were predominantly hypoechoic with a halo sign in two cases. No diffuse involvement of the liver was observed, and no correlation between histological lymphoma subtyping and patterns of hepatic infiltration was found.
