  • Title: Massive ascites and severe pulmonary hypoplasia in a premature infant with meconium peritonitis and congenital cytomegalovirus infection.
    Author: Chan ES.
    Journal: Fetal Pediatr Pathol; 2020 Feb; 39(1):71-77. PubMed ID: 31198083.
    Abstract:
    Background: Meconium peritonitis (MP) is an infrequent prenatal complication. Association between MP and pulmonary hypoplasia has never been reported. Case Report: A female infant with antenatally diagnosed MP and ascites was delivered at 36 gestational weeks. She died shortly after birth due to pulmonary insufficiency. Autopsy confirmed the presence of MP and ascites, and additionally revealed intestinal malrotation, volvulus, necrosis and perforation, and pulmonary hypoplasia. Congenital cytomegalovirus (CMV) infection was also noted. This was an unexpected finding as the mother was tested negative for CMV IgM at 26 gestational weeks after sonographic detection of fetal ascites. Conclusions: This is the first reported case of lethal pulmonary hypoplasia in a neonate with MP-associated ascites complicated by congenital CMV infection. This case illustrates that a negative maternal CMV IgM might not be sufficient to rule out congenital CMV, and that a concomitant infectious etiology should always be considered even when a primary cause for fetal ascites (e.g., MP in this case) is identified.
