Hypertrophic pyloric stenosis

Discussion:

Abdominal x-ray and ultrasound of a child with hypertrophic pyloric stenosis. The stomach, with gas distended antrum mimics a double bubble sign. Note the paucity of gas in small and large bowel. 

Ultrasound demonstrates thick and elongated pylorus. 

These images are from Dr. Paula Brill's excellent pediatric radiology collection.

Dr. Brill is a professor in the department of radiology (pediatric section) at Weill Cornell.
