The right ovary is midline in position, large and heterogeneous measuring 6.7x 4.7 cm, mild pushing the uterus anteriorly and to the right side, with multiple small mainly peripheral follicles inside, one of them is hyperintense on T1W suggestive of blood or proteinaceous material. It is surrounded by a clear mild amount of fluid collection.
Slightly heterogeneous high signal intensity seen in T1W and central high signal on STIR represents congestion and edematous changes. No evidence of fatty component.
There is no normal enhancement seen in the right ovary after contrast administration.
The left ovary is normal in size, shape, and contour and shows a normal stromal enhancement pattern.
Features are highly in favor of right ovarian torsion with engorgement and hemorrhagic necrotic changes.
