Findings: X-ray prone cross-table beam with buttock up (figure 1):
1. No obvious rectal gas in pelvis.
KUB (figure 2):
1. Bowel loops dilatation with air content in abdomen,
predominantly right abdomen, suspicious a distended
sigmoid colon (arrow in figure 2).
Multidetector row CT scan of abdomen (focus on pelvis) with
maximum-intensity projection and without intravenous contrast
(figure 3):
1. Left side deviation of sacrum with lateral hemivertebra in S3
(arrow in figure 3).
Plain film radiography of right hand (figure 4):
1. Duplication of right thumb (arrow in figure 4), in favor of
preaxial (radial) polydactyly.
1.5 Tesla MRI of abdomen with T2 weighted echo train spin echo with
and without fat saturation, T1 weighted echo train spin echo,
T2/T1 true fast imaging with steady-state precession gradient
echo with fat saturation, and without intravenous contrast
(figure 5 and 6):
1. Dilatation of distal colon with somewhat bird beak appearance
in lower abdomen, about 3.0cm in rectal pouch-perineal
distance, suggesting high anorectal malformation (figure 5).
2. Presence of air-fluid level within the distal colon with some
short T1 and T2 materials deposition (arrow in figure 5),
suggesting meconium-packed pouch.
3. No abnormal finding in remaining abdomen, including both
kidneys (white arrows in figure 6) and non-distended bladder
(yellow arrow in figure 6).
4. No abnormal finding in spine (red arrow in figure 6) form
current images.
Distal colostogram with water soluble contrast after diverting
colostomy (figure 7 and 8):
1. Early opacity of bladder (arrows in figure 7), suggesting
rectourinary fistula.
2. Distal tapering of colon with somewhat bird beak appearance
(figure 8).
