Overview
On abdominal X-ray, gastrointestinal stromal tumor is characterized by soft tissue density displacing bowel loops.
Abdominal X-ray
- Abdominal X ray is not routinely indicated in patients of GIST as their findings are quite non-specific. However, they may be indicated in patients who present with severe abdominal pain indicating intestinal obstruction or perforation. Findings on an abdominal X ray include:
- Dilated loops of bowel
- GIST can appear as large, soft tissue density displacing bowel loops
- Air-fluid level (intestinal obstruction)
- Air under diaphragm (bowel perforation)
- Other than the plain abdominal X ray, patients who develop symptoms can also be evaluated with a barium x-ray (upper and lower GI series). Patients with dysphagia are evaluated with barium esophagogram and patients with constipation are evaluated with barium enema. Findings on upper and lower GI series include:[1]
- GISTs appear as an elevated and sharply demarcated filling defect
- Smooth contour of overlying mucosa unless complicated by an ulceration
- Lower GI GIST can have decreased caliber of colon
