Ileal atresia


The findings are most consistent with either meconium ileus or jejunoileal atresia. Meconium ileus might be the favored diagnosis because of the multiple filling defects. However, at surgery, mid/distal ileal atresia was confirmed. 

It is important to remember that jejunoileal atresia is an acquired in-utero phenomenon secondary to ischemia/infarction and therefore, depending on when it occurs, meconium may have passed into the colon.
