Appearance of a double bubble in XXXX : a case report.

@entity1318 @entity384 @entity1 @entity4558
INTRODUCTION: @entity1318 is characterized by failure of the lower esophageal sphincter to relax in response to swallowing and by an absence of peristalsis in the esophageal body. Absence of a gastric air bubble is a well known radiological finding. @entity384 results in reappearance of the gastric bubble. CASE PRESENTATION: We report the case of a 43-year-old Indian @entity1 with @entity1318 whose chest X-ray at the time of presentation showed an air bubble in the gastric region causing a diagnostic quandary. Successful dilatation of the lower esophageal sphincter resulted in the appearance of another air bubble in the gastric region. Proper analysis showed that the first bubble was actually a colonic air bubble of the @entity4558 and the appearance of the second bubble was the anticipated gastric air bubble. CONCLUSION: In @entity1 presenting with @entity1318 , a colonic air bubble may be seen in the gastric region causing diagnostic difficulty. In these @entity1 , a gastric air bubble may appear after pneumatic dilatation. At the end of the procedure, there will be two air bubbles ("double bubble"): a colonic and a gastric air bubble. To our knowledge, this finding has not been reported in the literature thus far.
