Ultrasound Interactive Case Study: Unusual First Trimester Appearance

Case Presentation by: Sue Davies, Mermaid Beach, Australia - November 2000

 

 

History:

The patient is a 22 year old woman in her first pregnancy. The CRL showed an 8 week 5 day baby with heart rate of 176bpm. 

 

Ultrasound Findings:

The oval, anechoic areas on either side of the spine are something my colleagues and I have not encountered before. It was difficult to discern definitively whether they are within the thorax or abdomen. I could not define the diaphragm. The renal arteries were not seen. All other aspects of the pregnancy appeared within normal limits.

Follow-up:

I would like to hear if anyone has any ideas as to the significance of these findings. The girl has been referred for follow-up at a tertiary referral centre.
