US of low anorectal malformation
CXR AP (left) shows a hemivertebra at L1 causing spinal curvature convex left. Transverse US of the pelvis (above right) shows in the midline anteriorly an anechoic fluid-filled bladder with a round echogenic stool-filled rectum posterior to it while a transverse US of the perineum (below right) shows a very short distance between the calipers superiorly on the skin and inferiorly on the anterior wall of the rectum.

The diagnosis was low anorectal malformation and congenital scoliosis.
