Right ovarian mass with uniformly low T2 and high T1 signal, low signal on DWI.  Appearance in keeping with an endometrioma. Several normal ovarian follicles are noted adjacent to the endometrioma.

There is a further small focus of high T1 signal in the pouch of Douglas (best appreciated on the sag T1 fat sat sequence), suggestive of the presence of deep endometriosis.
