Abnormal position of pylorus in cranial abdomen on right lateral thoracic image
GDV (or at least volvulus, with only moderate dilatation of stomach)
Megaesophagus is likely secondary to the GDV, although other differentials for megaesophagus are possible
Aspiration pneumonia secondary to megaesophagus, regurgitation, vomiting
This case basically tested satisfaction of search. If the candidate missed the GDV, the case was essentially failed, although partial credit was awarded for description of the megaesophagus and aspiration pneumonia.
A right lateral view of the abdomen was available on request (last image), although full credit was given for the diagnosis of the GDV if it was diagnosed without the abdomen view.
