Normal size anteverted uterus. The endometrium has a smooth contour and is not thickened.

A T2 hyperintense, non-enhancing nodular component posteriorly is suggestive of a Rokitansky nodule and there are several scattered foci with similar signal characteristics throughout the lesion. There are no features concerning for malignancy. Left ovarian tissue is noted along the anterior aspect of the mass.

Normal right ovary with no follicles present.
