Here we have a prior CXR of this patient.
The AP-film shows a right paratracheal mass.
The azygoesophageal recess is not identified, because it is displaced and parallels the border of the right atrium.
The large round density in the left lung is the result of aspiration.
Notice the massive dilatation of the esophagus on the CT. #Clinical #Radiology #CXR #CTChest #Achalasia #DilatedEsophagus #Dilated #Esophagus #Aspiration #RadiologyAssistant
