Early low rectal cancer staging. a High-resolution axial T2WI baseline staging shows a low-lying posterior lesion extending from 2 to 10 o’clock confined to the rectal wall with no signs of intersphincteric plane involvement (arrow).

A watch-and-wait approach was attempted. Two years of follow-up show no regrowth
