|X-ray of a newborn with meconium pseudocyst resulting from bowel perforation. In this case the cause was astresia of the terminal ileum. There is a fine rim of calcification surrounding the big pseudocyst which shifts the other intestinal structures outwards.|
Meconium peritonitis refers to rupture of the bowel prior to birth, resulting in fetal stool (meconium) escaping into the surrounding space (peritoneum) leading to inflammation (peritonitis). Despite the bowel rupture, many infants born after meconium peritonitis in utero have normal bowels and have no further issues.
Infants with cystic fibrosis are at increased risk for meconium peritonitis.
