“…The fetal colon is visualized at 22 weeks' gestation as a hypoechoic area in the periphery of the fetal abdomen; peristaltic movements are demonstrated less clearly than in the small bowel. 10 Small bowel obstruction is associated with bowel loops having an internal diameter of more than 7 mm in combination with strong peristaltic movements. Obstruction of the large bowel is not always visible, since fluid is reabsorbed at the level of the colonic mucosa, leading to little or no distention of proximal bowel loops.…”

Fetal bowel obstruction has a prevalence of 1 in 3000 to 5000 live births. Ultrasonographic diagnosis is made by demonstrating distended loops of bowel. Echogenic bowel, defined as small bowel more echogenic than liver or bone, has been associated with congenital infections, cystic fibrosis, chromosomal abnormalities, and bowel obstruction. Fetal ascites, defined as fluid in the peritoneal cavity partly surrounding the liver and bladder, also has been associated with bowel obstruction. We present a case of jejunal atresia whose presenting appearance consists of echogenic bowel, transient ascites, and massive dilatation of intestinal loops.
