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
- Eccentric or circumferential wall thickening >5 mm[1]
- Peri-esophageal soft tissue and fat stranding
- Dilated fluid and debris filling the esophageal lumen is proximal to an obstructing lesion
- Tracheobronchial invasion appears as displacement of the airway (usually the trachea or left mainstem bronchus) as a result of mass effect by the oesophageal tumour
- Aortic invasion
Staging usually begins with a computed tomography (CT) scan to evaluate for the presence of metastatic disease. However, with increasing availability, positron emission tomography (PET) CT fusion scanning may be more accurate for the detection of stage IV disease, and can be used as an initial staging assessment
