Multiple CT findings have been described in ovarian torsion [27, 14, 31, 32] :

  • Enlarged adnexal structure (>5cm)

  • Thick, straight blood vessels draped around the lesion

  • Complete absence of enhancement

  • Hemorrhage or gas in the torsed lesion

  • Misplacement of the torsed structure (to the midline or contralateral side)

  • Deviation of the uterus to the involved side

  • Infiltration of the periadnexal fat

  • Tubal thickening

  • Thickened vascular pedical with engorged vessels
