Figure 3.

Near complete response. (a/b) Distal tumour outlined with dotted line with extramural extension on sagittal and axial T2-weighted imaging with invasion into the levator muscle (arrow in a). (c) After chemoradiation on axial T2-weighted imaging, a full thickness fibrosis is found with heterogeneous signal (white arrows in c). Endoscopy (e) shows an almost completely healed scar with central depression and a flat ulcer <1 cm (white arrows), surrounded by teleangiectasia. On DWI and ADC map (d/f) no restriction is found, only luminal T2 shine through (white arrow). ADC, apparent diffusion coefficient; DWI, diffusion-weighted imaging.
