Stage IIIB endometrial carcinoma with vaginal involvement. There is a large tumour with extension through the myometrium into the serosa. On the sagittal (a) and axial (b) T2W MR images, there is a nodule (arrow) with intermediate T2 signal caudally at the level of the vagina on the right, in keeping with a drop metastasis. On axial post-contrast T1W image (c), the drop metastasis is an hypoenhancing lesion (arrow) compared to the hyperenhancing vaginal mucosa and muscular layer. This was diagnosed with biopsies confirming endometrioid carcinoma
