Paratracheal Air Stripe Sign: A Useful Chest X-Ray Finding for Diagnosis in Patients with Esophageal Achalasia
PASS represents a novel and clinically useful chest X-ray feature associated with esophageal achalasia. Its relatively high prevalence, even among cases missed by EGD, and low occurrence in non-achalasia patients suggest that routine assessment of PASS in chest X-rays may aid early detection and timely referral for definitive diagnosis, particularly in primary care settings.
