摘要

This case highlights a rarely imaged phenomenon, captured as the patient retched during a multiphase CT scan, with venous phase images showing transient aortic collapse. This could lead to false positive interpretation of aortic stenosis. Knowledge of this phenomenon, review of multiphase CT images, and discussion with technologists can avoid false positive diagnoses of aortic stenosis.
