Hiperplasia nodular linfoidea hepática. Aportación de la resonancia magnética con doble contraste

Nodular lymphoid hyperplasia, also known as pseudolymphoma of the liver, has been little reported in the current literature (37 cases) and requires differential diagnosis with other focal lesions of the liver. The development of this entity has been associated with other extrahepatic tumors, chronic liver disease, autoimmune disease, and other chronic inflammatory processes. Because pseudolymphoma of the liver usually shows hypervascularity on dynamic studies, it must be differentiated from other lesions-mainly metastatic lesions and hepatocarcinomas-in imaging studies, in which these lesions are usually an incidental finding. We report two cases of pseudolymphoma of the liver, studied with double-contrast (gadolinium + iron oxide) magnetic resonance imaging in two women aged 58 and 59 years old with a history of advanced primary biliary cirrhosis and advanced liver cirrhosis, respectively.
