Large complex left ovarian cyst. Presents for further characterization. PELVIS:UTERUS, ADNEXA: Anteverted retroflexed uterus. The endometrium is normal in thickness. The inner myometrium/junctional zone is thickened with an ill-defined inner/outer myometrial junction compatible with diffuse adenomyosis.There is a 7.8 x 6.8 cm left adnexal mass extending into the rectouterine pouch displacing the uterus anteriorly demonstrating hyperintensity on T1-weighted imaging sequences with hypointensity on T2-weighted imaging sequences compatible with an endometrioma.Otherwise the right adnexa and left ovary are unremarkable.Numerous cervical nabothian cysts.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Degenerative disc disease at L5-S1.OTHER: No significant abnormality noted.
