Meconium peritonitis (MP): Chemical peritonitis resulting from in utero bowel perforation that leaks sterile meconium & digestive enzymes into peritoneal cavity
Meconium cyst: Meconium + fluid contained by fibrous membranes in setting of MP
Meconium pseudocyst: Meconium + fluid contained by membranes partly derived from muscular layer of intestine
