Intra-Uterine Perforation Presented as a Giant Cystic Abdominal Mass in a Neonate: A Giant Meconium Pseudocyst.

A meconium pseudocyst is formed following meconium peritonitis. At present, antenatal diagnosis and planned management of meconium pseudocyst have reduced the mortality rate significantly. We presented a case of a neonate with abdominal distension and non-passage of meconium who experienced respiratory distress and was taken for exploratory laparotomy at a tertiary care center due to suspected bowel perforation. The neonate was diagnosed with a meconium pseudocyst intraoperatively as maternal ultrasound and ultrasound of the abdomen of the neonate after birth failed to make a definitive diagnosis; even an X-ray abdomen did not reveal pathognomonic egg-shell calcification. An interesting aspect of this case is the mother's complex obstetric history, which compelled us to conjecture whether it was possible to predict the chances of meconium peritonitis and take steps to prevent it. It must be noted that, despite rigorous research, the researchers could not find reliable literature co-relating the obstetric history of the mother with the formation of a meconium pseudocyst in the neonate.
