Enlarged left ovary (7.5 x 6.5 x 5.5 cm) of intermediate signal intensity on T1WI, low signal intensity on T2WI, containing a corpus luteal cyst as well as peripherally displaced follicles with twisted vascular pedicle giving the appearance of a whirlpool sign. The postcontrast sequences show a thin rim of peripheral enhancement (infarcted ovary). Mild intraperitoneal effusion.
The right ovary shows a normal appearance with a follicle of 2.7 cm in diameter.
The uterus is of normal shape, and size with thickening of the endometrium-myometrium junctional zone (thickness=15 mm) in keeping with adenomyosis.
