From: Radiology–pathology correlation of endometrial carcinoma assessment on magnetic resonance imaging
Endometrial carcinoma in a patient with adenomyosis. Axial post-contrast T1W GRE (a), axial T2W (b) and axial ADC map (c) images show the tumour (*) in the endometrial cavity. There is diffuse adenomyosis with background myometrial cysts (arrows). Myometrial cysts are hyperintense on T2 weighted imaging without significant diffusion restriction. Tumour can colonise adenomyosis and is not considered to be muscle invasive if confined to the adenomyosis. Histology (H&E stain, 4 × magnification, d) showed colonisation of areas of adenomyosis by complex crowded tumour cells (arrow), but this could not be preoperatively distinguished from normal adenomyosis on imaging
