We present a case of a 77-year-old woman with dysphagia and regurgitation whose barium esophagram demonstrated a characteristic \u201cnutcracker\u201d appearance of the distal esophagus. Despite this striking radiographic finding, peristalsis was preserved, and a barium tablet traversed the segment without obstruction. These features argue against classic diffuse esophageal spasm and instead suggest a hypercontractile motility disorder. This case highlights the role of barium esophagram as a complementary diagnostic tool while emphasizing that definitive classification of esophageal motility disorders requires high-resolution manometry.<\/jats:p>","DOI":"10.56305\/001c.163429","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T12:48:28Z","timestamp":1782910108000},"source":"Crossref","is-referenced-by-count":0,"title":["Hypercontractile Esophagus: An Underrecognized Cause of Dysphagia with a \u201cNutcracker\u201d Appearance on Barium Esophagram"],"prefix":"10.56305","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-2895-9043","authenticated-orcid":true,"given":"David K.
