Wan-Ling Miriam Wu* and Chiao-Hsuan Chien
A 67-year old man presented with dysphagia for several weeks. Endoscopy was performed for suspected esophageal lesion, and an upper esophageal cancer was found and proved by biopsy. A contrast enhanced computed tomography (CT) was performed for cancer staging. Post-contrast CT demonstrated concentric esophageal wall thickening which was compatible with the presence of esophageal cancer. Post-contrast CT also revealed an avidly and heterogeneously enhancing nodule in anterior mediastinum. This nodule demonstrated high attenuation on pre-contrast CT. The rest of the CT exam showed no remarkable findings.
