Double sigmoid atresia with meconium pseudocyst masquerading as a mesenteric cyst

Sigmoid atresia is one of the rarest cause of neonatal intestinal obstruction. We report an antenatally diagnosed mesenteric cyst in a neonate that was subsequently diagnosed as a meconium pseudocyst with double sigmoid atresia. A localized type 4 atresia or a colonic atresia associated with meconium pseudocyst has not been reported in the literature to date.Keywords: atresia, obstruction, pseudocyst, sigmoid colo
