ABSTRACT
La hiperplasia nodular linfoidea (HNL) o seudolinfoma hepático, es una lesión hepática muy poco reportada en la literatura actual (37 casos), que plantea el diagnóstico diferencial con otras lesiones focales del hígado. Su aparición se ha asociado a otros tumores extrahepáticos o al contexto de una hepatopatía crónica, enfermedad autoinmune o a otros procesos inflamatorios crónicos y dado que suele presentar un carácter hipervascular en los estudios dinámicos, debe de ser diferenciada de metástasis o hepatocarcinomas, fundamentalmente, en las pruebas de imagen, donde se presentan de un modo incidental. Presentamos 2 nuevos casos de HNL, estudiados mediante RM con doble contraste (gadolinio + óxido de hierro) en 2 mujeres de 58 y 59 años, con antecedentes de cirrosis biliar primaria y hepática evolucionadas (AU)
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 lesionsmainly metastatic lesions and hepatocarcinomasin 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 (AU)

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.
