Case Discussion

Focal retroplacental mass/bulge that is isoechoic to the uterus. Differential considerations include:

Diagnosis

Follow-up was performed to confirm the diagnosis of uterine contraction. Note the resolution of the retroplacental bulge on follow-up imaging.

Doppler assessment is also useful (not shown here):

  • hematoma- there is no Doppler flow
  • uterine contraction- increased RI
  • myoma - little Doppler flow
