All of the following imaging finding is diagnostic of Adenomyosis: (A) Thickness of low signal intensity junctional zone >12mm on T2 -  weighted images., (B) Rain shower appearance of myometrium with coarsened echotexture., (C) Linear striations and subendometrial echogenic nodular appearance on USG., (D) Calcifications seen on CT - Scan.
Answer is D. CT - is insensitive for adenomyosis. Presence of calcifications strongly favours fibroids rather than adenomyosis.
