Case of the Week: Ovarian Torsion (Ultrasound)

In this radiology lecture, we discuss the ultrasound appearance of ovarian torsion.

Key points include:

  • Rotation of ovarian vascular pedicle with obstruction to venous outflow and arterial inflow.
  • Enlarged, heterogenous ovary due to hemorrhage and edema.
  • Small peripheral cysts with “follicular ring” sign: Thick, hyperechoic rim surrounding follicles of torsed ovary.
  • Classically, absent vascular flow.
  • However, up to 60% of patients with torsion have normal color Doppler findings, and arterial flow may even be preserved!
  • Most common finding is decreased or absent venous flow.
  • Twisted vascular pedicle: Most definitive sign of torsion, present in up to 88% of patients.
  • “Whirlpool” sign: Flow within the twisted vascular pedicle.

Case of the Week: Cecal Volvulus (X-ray & CT)

In this inaugural case of the week radiology lecture, we discuss the imaging appearance of cecal volvulus!

Key points include:

  • Cecal volvulus occurs when there is twisting of cecum around the mesentery with proximal large bowel obstruction.
  • Cecum normally <9 cm, rest of large bowel <6 cm.
  • Topogram (scout view) extremely helpful.
  • Vector typically points towards LUQ, but instead of worrying about vector direction, look for proximal dilated small bowel (as opposed to large bowel) to differentiate from sigmoid volvulus.
  • Complications include pneumoperitoneum = bowel perforation (Rigler’s sign, falciform ligament sign) and pneumatosis = cecal ischemia.
