A 51-year-old man with esophageal squamous cell carcinoma, and late stage (T3) case wrongly diagnosed as early stage (T1) by CT and correctly diagnosed by MRI. (A) Arterial phase CT shows the esophageal contour is smooth, the lesion (red arrow) invades the muscularis mucosae (blue arrow) alone, enhanced muscularis mucosae and muscularis propria (yellow arrow) is intact and thus staged as T1. (B)T2WI-msTSE shows the lesion (red arrow) invades the adventitia. (C) On DWI, b = 700 the lesion (red arrow) is hyperintense. (D) 3D-GRE shows enhanced muscularis mucosae (blue arrow) and the muscularis propria of hypointensity (yellow arrow) almost disappear, MRI shows lesion (red arrow) in T3 staging. (E) EUS shows tumor (red arrow) invading adventitia resulting in thinning adventitia (white arrow) and consistent with T3 staging on EUS. (F) H&E stained section at × 40 microscopy confirm that the tumor (red arrow) invades adventitia (white arrow), consistent with T3 stage
