Sonographic demonstration of multiple intrahepatic meconium masses in a newborn with meconium peritonitis.
We report on a patient with atresia of the colon transversum and a large meconium pseudocyst adherent to the liver. Sonography additionally revealed multiple cystic structures due to intrahepatic meconium masses. Surgical evacuation of the meconium pseudocyst resulted in massive diffuse hemorrhage from the liver which could not be stopped. The child died intraoperatively due to hemorrhagic shock. Histologically the intrahepatic meconium masses were surrounded by various degrees of necrosis and hemorrhage without a well-defined capsule of fibrous granulation tissue.
