CT of nodular hyperplasia of the liver in non-Hodgkin lymphoma.

During follow-up of non-Hodgkin lymphoma in a 60-year-old man, multiple hepatic small lesions were incidentally found by sonography. Dynamic CT disclosed enhancing masses in both the right and left lobes and faint arterioportal shunting in the left lobe of the liver. These findings were confirmed by angiography. Portal hypertension was, however, not present. Exploratory laparotomy revealed nodular regenerative hyperplasia of the liver. The nontumorous liver was normal.
