Objective: To present an unusual case of meconium peritonitis diagnosed during prenatal period and its postnatal outcome. Conclusion:MP needs to be considered if the fetus has isolated ascites with internal echoes and progresses to hydrops, as it is one of the treatable causes of hydrops fetalis. Perinatal morbidity and mortality rate is about 80%. In-utero diagnosis and timely intervention are associated with favourable perinatal outcome. Neonatal septicemia is the most common cause of postoperative morbidity and mortality with an added risk of prematurity as was in our case.
