Oblique axial post-contrast 3D T1W GRE MR (a), oblique axial T2W MR (b), sagittal early phase DCE T1W MR (c) and macroscopic (d) images of a large endometrial carcinoma. There is a large exophytic intracavitary tumour with distension of the endometrial cavity. In this situation, it is difficult to estimate where the endometrium/myometrium interface should be and the depth of invasion. In this case, the tumour was extending into the outer half of the myometrium (stage 1b) at the posterior aspect on final pathology. The invasive front of the tumour (arrow) shows early peritumoural enhancement and has slight irregularity at the interface with the normal myometrium and blurring of junctional zone’s low T2 signal
