25 year old male Known MDR TB for past 4 years , on ATT with second line agents, smear and culture negative for last 1 year.Describe radiological findings and comment on activity?

Ribs removal gives away the surgical intervention.Right upper lobectomy has left a cavity like residual space.Left upper lobe infiltrates are fibrotic scars. Mostly not an active disease.In any case that is decided by sputum/BAL better than radiology.
