title: Unusual pharyngeal lesion causing dysphagia.
abstract: A 58-year-old man was evaluated for a 42-year complaint of a pharyngeal foreign body sensation whenever he ate. Examination revealed normal anatomy at rest but diffuse hypopharyngeal distension with Valsalva's maneuver. His past history was remarkable for an infectious illness, possibly diphtheria. We speculate that this unusual case most likely represents a postdiphtheritic selective pharyngeal paralysis and present his case, radiographic findings, and a discussion of the differential diagnosis.
