Hi,
It means wall of large intestine is thickened.
Almost whole length of large intestine involved starting from ileocolonic
anastomosis (junction of terminal part of
small intestine with large intestine)
upto rectosigmoid (junction between terminal part of large intestine with
rectum) junction.
[Patient may have undergone
abdominal surgery where part of large intestine with or without some terminal part of small intestine is removed and remaining part of large intestine sutured with terminal part of small intestine].
Thickening is more prominent in middle portion (transverse and proximal descending colon) large intestine.
The cause for thickening may be inflammatory, infection or due to
pseudomembranous colitis (infection of large intestine due to particular organism clostridia)
Thumbprinting is a radiographic sign of large bowel wall thickening.
Clinical correlation is needed it means correlate the CT findings with patient's clinical condition (patient's symptoms, physical examination findings).
Hope this may be helpful to you.
If so do vote.
