Overview
Abdominal CT scan may be diagnostic of small intestine cancer. Findings on CT scan suggestive of small intestine cancer is intrinsic mass with a short segment of bowel wall thickening.
CT Scan
- CT is the modality of choice for staging the disease by identifying primary tumor, assessing local, nodal and distant spread.
- CT can help in differentiating the small intestinal cancers. Different tumors have different appearance on CT:[1]
- CT scan can show intrinsic mass with a short segment of bowel wall thickening.
- Invasion of retro peritoneal fat planes, pancreatic and biliary duct, vascular encasement, lymph nodal and distant metastases is common in later stages.
- In Peutz-Jeghers Syndrome, non-neoplastic lesions may resemble small intestinal neoplasm on CT.
| Tumors | Findings on CT |
|---|---|
| Adenocarcinmoa |
|
| Carcinoid tumors |
|
| Non-Hodgkin lymphoma |
|
| Gastrointestinal stromal tumors(GISTs) |
|
| Lipoma |
|
| Malignant metastasized tumors |
