Findings: The left adnexal cystic structure is torsed in abnormal location (sits abnormally high in the midline/ right lower quadrant - enlarged ovary in an abnormal location).

Objectives:

• To review female pelvic anatomy

• To learn the signs that should prompt suggestion of ovarian torsion on CT scan

Protocolling:

• Ultrasound test of choice when torsion suspected clinically

• Usually seen when CT performed for non-specific abdominal pain

Key Points:

• Anatomy:

  • Review female pelvic anatomy on CT

  • Follow ovarian vessels to help identify region of ovaries

• CT Findings:

  • “Twisted pedicle” is specific but only occasionally seen

  • ENLARGED ovary (often with a mass) in ABNORMAL location

  • Edematous ovary with peripheral follicles (difficult to resolve on CT)
