Meconium pseudocyst formation is a complication that can occur with meconium peritonitis.
It occurs when the extruded meconium becomes walled off within the peritoneal space.
May be seen as a rim calcified mass within the abdomen.
Meconium pseudocyst may be sonographically seen as a relatively well-defined hypoechoic mass often surrounded by an echogenic calcified wall 2.
