A hiatal hernia is the most common cause of displacement of the

Notice the deviation of the azygoesophageal line on the PA-film. It is caused by a hiatal hernia. #Clinical #Radiology #CXR #AzygoesophagealRecess #Azygoesophageal #Recess #Hiatal #Hernia #RadiologyAssistant

Another common cause of displacement of the azygoesophageal line is subcarinal lymphadenopathy. Notice the displacement of the upper part of the azygoesophageal line on the chest x-ray in the area below the carina. This is the result of massive lymphadenopathy in the subcarinal region (station 7). There are also nodes on the right of the trachea displacing the right paratracheal line. #Clinical #Radiology #CXR #Lateral #Subcarinal #Lymphadenopathy #Azygoesophageal #Displacement #RadiologyAssistant

Azygoesophageal recess The most important mediastinal line to look for is the azygoesophageal line, which borders the azygoesophageal recess. This line is visible on most frontal CXRs. The causes of displacement of this line are summarized in the table. #Diagnosis #Radiology #CXR #Azygoesophageal #Recess #Displacement #Differential #RadiologyAssistant

Study the CXR of a 70-year old male who fell from the stairs and has severe pain on the right flank.. Notice on the PA-film the absence of the little finger on the right and on the lateral view the increased density over the lower vertebral column. What is your diagnosis? There is a right lower lobe atelectasis. #Clinical #Radiology #CXR #Lateral #RLL #Atelectasis #RadiologyAssistant

There is displacement of the azygoesophageal line both superiorly an inferiorly. There is an air-fluid level (arrow). Combined with the above this must be a dilated esophagus with residual fluid. The final diagnosis was achalasia. The density on the left in the region of the lingula is the result from prior aspiration pneumonia. #Clinical #Radiology #CXR #Achalasia #DilatedEsophagus #AirFluidLevel #Aspiration #RadiologyAssistant

Nontuberculous mycobacteria Nontuberculous mycobacteria, also known as atypical mycobacteria, are all the other mycobacteria which can cause pulmonary disease resembling TB. Here a patient with active disease in both upper lobes due to infection with atypical mycobacterium. Notice the air-fluid level indicating pus within the cavity (arrow). #Clinical #Radiology #CXR #Lateral #NonTuberculosis #Mycobacteria #NTM #Cavity #AirFluidLevel #RadiologyAssistant

The location of the cardiac valves is best determined on the lateral radiograph. A line is drawn on the lateral radiograph from the carina to the cardiac apex. The pulmonic and aortic valves generally sit above this line and the tricuspid and mitral valves sit below this line (4). On this lateral view you can get a good impression of the enlargement of the left atrium. #Clinical #Diagnosis #Radiology #CXR #Lateral #Valve #Replacement #Localization #Mitral #MVR #RadiologyAssistant

First study the images and then continue reading. On the lateral view there is a mass-like lesion that is pleural-based. The first impresson is, that this is a pleural lesion. #Clinical #Radiology #CXR #Lateral #RoundedAtelectasis #Rounded #Atelectasis #RadiologyAssistant

Septic emboli On a follow up CXR only a small lungcyst is seen. #Clinical #Radiology #CXR #Lateral #Cyst #RadiologyAssistant

The azygoesophageal recess is the region inferior to the level of the azygos vein arch in which the right lung forms an interface with the mediastinum between the heart anteriorly and vertebral column posteriorly. It is bordered on the left by the esophagus.
