Findings: The ultrasound findings demonstrated the fetus to be in a cephalic postiton, placenta is visulaized posterior, the cervix is closed and AFI is calculated 12.4.  The ultrasound images demonstrate during survey views dilated small bowel loops displaying active peristalisis. The bowel loops do not appear echogenic. 
Diagnosis: This case is most likely to be Meconium Ileus
Discussion: Meconium Ileus is a small bowel disorder when a baby's first stool called meconium is blocking the last part of the baby’s small intestine the ileum. This can happen when the meconium is thicker and more sticky than normal.  Most of these cases occur with newborns that have cystic fibrosis.  Meconium begins to accumulate in the fetal bowel around the second trimester.  The normal small bowel will appear echogenic.  Symptoms of Meconium can be a swollen belly/ abdomen. Meconium Ileus is the third most common form of neonatal bowel obstruction after atresia and malrotation
