Sample item

Which ultrasound feature supports hypertrophic pyloric stenosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Thickened elongated pyloric muscle

Pyloric ultrasound demonstrates an elongated hypertrophied pyloric muscle in infants with progressive non-bilious projectile vomiting.

Option by option

  • A. Bilateral pleural fluid

    Pleural fluid is thoracic pathology.

  • B. Thickened elongated pyloric muscle (correct)

    Correct: muscle thickening and elongation are diagnostic clues.

  • C. Dilated appendix only

    Appendix assessment is unrelated.

  • D. Absent renal cortex

    Renal cortex does not diagnose pylorus.
