Today’s case is an 11 year old male neutered Rhodesian Ridgeback who has been choking on saliva and bringing up white foam.
Everyone has been writing great interpretations of these radiographs in the comments section, keep it up! It’s good practice to come up with findings and differential diagnoses on unknown cases.
Megaesophagus and a cranial toraxic mass
The esophagus is diffusely distended with gas. The right middle lung lobe is opaque. On the lateral views there is a soft tissue opacity cranial to the heart.
Looks like megaesophagus with aspiration pneumonia.
So the votes so far favor three major abnormalities that both readers comment on above. Where exactly is the mass cranial to the heart?
The location is suggestive of thymoma, which can also be the cause of the megaesophagus
The three abnormalities within the thorax were the megaesophagus, aspiration pneumonia, and cranial mediastinal mass. There is also a large mass on the outside of the body wall that some of you might have seen. And it’s always good to try to tie all of the abnormalities together to make one story.
Fantastic case! Any info on the mass outside the thorax? Maybe lipoma?
