Aim: To report on a rare case of meconium peritonitis (MP). Case Report: We report a case of G2P1L1 at 37 weeks of gestation, a post caesarean pregnancy with all prior normal ultrasound reports, came with complaints of decreased fetal movements. On ultrasound scan there was features suggestive of meconium peritonitis with small bowel perforation. She was delivered by emergency repeat caesarean section and the neonate underwent laparotomy on the first neonatal day. Discussion: Meconium peritonitis is a rare condition diagnosed in antenatal period which has a high neonatal morbidity and mortality. Meconium peritonitis is an aseptic chemical peritonitis caused due to in-utero bowel perforation, most frequently secondary to obstruction, often diagnosed by routine fetal ultrasound. Conclusion: Early diagnosis and treatment are the keys to successful management of MP.
