Gas in the Colon

The colon (overlaid in purple in the right image is filled with gas.  In this instance it is abnormally distended with gas either due to a distal large bowel obstruction  or a condition called large bowel ileus or Ogilvie’s syndrome.  The image on the left is a scout film from a CT scan that is performed prior to the acquisition of the axial images.
