Endometrial cancer extending into the endocervical canal. a Sagittal and b oblique axial T2-weighted images demonstrate an intermediate signal intensity mass (black arrow). This lesion was thought to be confined to the endocervical canal but on histology there was minimal invasion of tumour into the cervical stroma (FIGO II). In retrospect, there is some thinning of the low signal intensity cervical stroma (white arrow). Minimal invasion of the stroma is difficult to report confidently and remains a potential pitfall
