Case of the Week: Septate Uterus (MRI)

Listen Later

In this radiology lecture, we discuss the MRI appearance of septate uterus, and explain how to differentiate from other uterine anomalies.

Key points include:

  • Most common müllerian duct anomaly (55%): Septal reabsorption abnormality.
  • Ultrasound and MRI provide assessment of external uterine contour and presence of renal anomalies.
  • Hysterosalpingogram of limited value, cannot reliably differentiate between subtypes.
  • On MRI, uterine fundus is typically convex or minimally indented: Fundal cleft less than 1 cm.
  • Midline septum of variable length, may be muscular or fibrous.
  • Important to differentiate type of septum as may alter surgical approach.
  • Compared to bicornuate uterus, higher incidence of reproductive complications (miscarriage).
  • Treatment: Resection of septum if recurrent fetal loss.
