Large well-defined solid cystic lesion with peripheral enhancing solid component and septations is seen in the midline likely arising from left adnexa, abutting the urinary bladder inferiorly and displacing the rectosigmoid junction posteriorly. The mass is abutting the small bowel loops superiorly and left external iliac vessels. Both ovaries are not separately visualised. There is suspicion of a whirl sign medially and posteriorly to the mass.
No evidence of calcification/Fat attenuation lesion within.
Uterus appears significantly compressed and displaced by the lesion
Impression: Features are highly suggestive of ovarian torsion.
