Prenatal sonographic diagnosis of meconium peritonitis: a case report.

A case of meconium peritonitis that was diagnosed ultrasonographically in the third trimester is presented. Fetal ascites, intra-abdominal calcification, left communicating hydrocele, and polyhydramnios were detected on antenatal ultrasonography. Specks of calcification were also demonstrated on abdominal radiography postnatally. Laparotomy confirmed the diagnosis of perforated terminal ileum with meconium peritonitis. The obstetric and neonatal implications of meconium peritonitis are discussed with literature review.
