A 67-year-old woman with esophageal squamous cell carcinoma, and Early stage (T1) case wrongly diagnosed as late stage (T3) by CT and correctly diagnosed by MRI. (A) Arterial phase CT shows the partial high density muscularis mucosae (blue arrow) and muscuaris propria (yellow arrow) are interrupted, and the lesion (Red arrow) is staged as T3. (B)T2-msTSE shows lesion (red arrow) with intact hypointensity muscularis propria (yellow arrow). (C) On DWI, b = 700, the lesion (red arrow) is hyperintense. (D) 3D-GRE shows mucosal lesion (red arrow) with enhanced muscularis mucosae (blue arrow) and muscularis propria of hypointensity (yellow arrow), MRI shows lesion in T1 staging. (E) EUS shows tumor (red arrow) invading muscularis mucosae with intact muscularis propria (yellow arrow) consistent with T1 staging on EUS. (F) H&E stained section at × 40 microscopy confirm that the tumor is located in the muscularis mucosae (blue arrow), consistent with T1 stage
