1.What is the abnormality seen in this chest radiograph
2. Give two likely causes for this condition
Answer
1) Air- fliud level in the left hemithorax (6)
2) Hemopneumothorax(2), pyopneumothorax (2)
Discusion
Collection of fluid in the pleural space with an air- fluid level is seen with lung abscess, hemopneumothorax and pyopneumothorax.
Lung abscess is characterized by a such collection with a well demarcated capsule and when the air fluid level is seen across the hemi thorax without a capsule it is due to hemopneumothorax and pyopneumothorax. These can arise as a rupture of lung abscess (pyopneumothorax) or following trauma ( hemopneumothorax)
