Air in the esophagus is unusual because it is collapsible. Its finding on a chest roentgenogram, particularly when not associated with a fluid level indicative of stricture, should strongly suggest systemic sclerosis (scleroderma). We describe a patient with scleroderma with intestinal pseudoocclusion and an air esophagogram. Study of chest roentgenograms of 83 patients with scleroderma, including those of 7 with pseudoocclusion, revealed no other instance of air esophagogram. This radiological sign, although rare, should suggest scleroderma and may be particularly useful in patients with "systemic sclerosis sine scleroderma."
食管内出现气体较为罕见，因为食管是可塌陷的。在胸部X线片上发现此情况，尤其是当不伴有提示狭窄的液平面时，强烈提示系统性硬化症（硬皮病）。我们描述了一名患有硬皮病且伴有肠道假性梗阻及食管积气造影的患者。对83例硬皮病患者的胸部X线片进行研究，其中包括7例伴有假性梗阻的患者，未发现其他食管积气造影的病例。这种放射学征象虽然罕见，但应提示硬皮病，对于“无硬皮的系统性硬化症”患者可能特别有用。
