Report

EXAM: Pyloric ultrasound (US)

INDICATION: 4-week-old female with vomiting and failure to gain weight.

TECHNIQUE: Multiple grayscale sonographic images were obtained of the gastric outlet and proximal small bowel.

FINDINGS:
There is abnormal muscular thickening and elongation of the pylorus. The pylorus is 5 mm in thickness and 23 mm in length. The pyloric channel is closed. Gastric contents are visualized, but on cine imaging, no contents are seen traversing the pyloric channel into the small bowel.

IMPRESSIONS:
Abnormal thickening and elongation of the pylorus without movement of gastric contents into the small bowel. These findings are compatible with hypertrophic pyloric stenosis.
