Patient Data

Age: 50
Gender: Male

Veiling opacity in the right hemithorax, most in keeping with a pleural effusion. 


Erect projection confirms the presence of a moderate-large pleural effusion. There is also a smaller left sided pleural effusion. 

Case Discussion

On supine projections, pleural effusions produced a "veiling opacity", which is due to pleural fluid preferentially collecting postoinferiorly in the pleural space. On erect films, pleural effusions are a basal opacity with a meniscus.
