Overview
CT scan may be used for staging of esophageal cancer. Findings on CT scan suggestive of esophageal cancer include eccentric or circumferential wall thickening, or peri-esophageal soft tissue and fat stranding.
CT
- For initial staging of esophageal cancer, CT may be used concomitantly with endoscopic ultrasound or positive emission tomography.[1]
- CT is used to determine the presence of metastatic disease, particularly within stage IV of the disease.
- CT can detect the following features:
- Eccentric or circumferential wall thickening >5 mm
- Peri-esophageal soft tissue and fat stranding
- Dilated fluid and debris filling the esophageal lumen
- Tracheobronchial invasion
- Aortic invasion
| CT | Sensitivity | Specificity |
|---|---|---|
| Detection of celiac lymph node metastases | 50% | 83% |
| Detection of regional lymph node metastases | 42% | 93% |
