Figure 1. Abdominal CT examination (axial section), circular wall thickening at the level of jejuno-ileal segment of the small intestine, leading to a narrowing of the lumen (large arrow). The intestinal dilatation ends at this level. SBF can be observed in the immediately proximal jejunum segment (double arrow) along with the fluid levels in the more proximal segments (small arrows).
Figure 2. Plain abdominal X-ray (a) and coronal reconstruction of abdominal CT image (b); for SBF extending through a length of 20 - 25 cm in the left quadrant of the abdomen at the level of the jejunal segment (arrow heads).
Figure 3. Abdominal CT examination (axial section): a) the terminal ileum segment has a normal diameter (arrow) while the proximal small bowel segments appear as dilated. SBF is present in the dilated segments immediately proximal to the terminal ileum (double arrow), while only fluids are present in the more proximal dilated segments (arrow heads). b) SBF appearance (double arrows) and proximally dilated small bowel segments filled only with fluid (arrow heads).
Figure 4. Abdominal CT examination (axial section); a) SBF appearance extending to the level of the terminal ileum (double arrow), with mild dilation of the more proximal segments (arrows). b) SBF extending to the level of the terminal ileum (double arrow).
Figure 5. Abdominal CT examination (axial section); a) SBF can be observed in the ileum segment (double arrows). b) the terminal ileum segment and distal segment to the obstruction site has a normal diameter (arrow heads) while the proximal small bowel segments appear as mild-dilated and filled only with fluid (arrow).
