Banana-Shaped Cerebellum at 13 weeks

Ultrasound case presentation by:
Allen Worrall, MD, RDMS
Fairbanks, Alaska, USA
September 2000

 

History
25 year old G2 P0 SAB1, 12w6d. Triple screen has not yet been done.

 

Ultrasound Findings
This looked like a "banana cerebellum" 13 weeks, however it is difficult to say with certainty what to expect at that gestational age. The transvaginal anatomy survey was otherwise unremarkable.

 

Follow-up at 23 weeks

The cerebellum appeared normal on follow-up examination without evidence of "banana" configuration.
