Summary
-
pathophysiology
- relatively high sensitivity for intra-abdominal
inflammatorypathology- many inflammatory processes will cause fat-stranding
- non-specific
- fat-stranding just means that there is inflammation close by
- common causes
- other causes
- ischaemia/infarction, e.g. omental infarction
- vascular, e.g. aneurysm
- relatively high sensitivity for intra-abdominal
-
investigation
- fat-stranding is primarily seen on CT
- inflammatory fat may be seen on US and MRI
Radiographic features
CT
The density of the affected fat changes. Usually fat is dark grey, but when there is oedema in the fat, the density increases and it becomes progressively lighter and progressively closer to the colour of muscle.
