ICD in situ in left hemithorax.
Left upper zone opacity consistent with previous CXR 3/7 ago. New opacity in lower zone suggesting early lower lobe consolidation although left hemidiaghram is still visible (i.e. no silhoutting yet).
Apical pyopneumothorax suggested by lack of lung markings with an air fluid level. This is distinguished from a lung abcess (rounded) by the characteristic lentiform shape. Since it doesn't unifromly cross the whole hemithorax this collection is probably loculated.
Given the history of this patient and presence of adjacent consolidation it is reasonable to say that this is a pyopneumothorax (versus hydro or haemopneumothorax) secondary to a lung abcess leaking into pleural space/bronchopleural fistula.
