TOP DIFFERENTIAL DIAGNOSES

• Cervical osteophytes (indentation)

image Large anterior cervical osteophytes can impinge on pharyngoesophageal junction, simulating cricopharyngeal achalasia
• Esophageal tumor

image Tumor at pharyngoesophageal junction may constrict lumen concentrically or eccentrically
