PRENATAL CYSTIC ABDOMINAL MASS REVEALING AN ENCYSTED MECONIUM PERITONITIS

Meconium peritonitis is a rare neonatal condition, often due to intra uterine bowel perforation. In some cases, peritoneal inflammation may lead to a pseudocyst formation. Prenatal diagnosis through ultrasound is important to ensure immediate post-natal treatment to enhance prognosis. We report the case of a 35-year-old woman, at term gestation, admitted for a fetal ultrasound before deliverance revealing a fetal peritoneal cystic mass with dilation of proximal small bowel, confirmed in post-natal imaging and surgery to be an encysted meconium peritonitis secondary to bowel atresia.
