Nodular regenerative hyperplasia of the liver: ultrasonographic appearance and echo-guided bioptic diagnosis.
Nodular regenerative hyperplasia of the liver is characterized by multiple and usually small nodules of hyperplastic hepatocytes surrounded by compressed atrophic liver cells. Given the small size of nodules and the preserved framework, the imaging techniques often show a normal liver and blind percutaneous biopsy is misinterpreted. The Authors report two cases of nodular regenerative hyperplasia diagnosed by ultrasound and percutaneous echoguided biopsy.
