well that looks like "crescent moon signs" with multiple aspergillomas in the cavitations left by the previous TB. it can be treated with oral itraconazole for months or with surgical excision
Hint : what u r seeing was actually a treatment method 4 TB in the 1950s, at a time when effective anti Koch's drugs were not available
Ok, this is very tricky and I don't see any more answers coming...so i will give the verdict and credit to Daniel for atleast trying The CT scan shows that the patient has previously been treated with plombage – the insertion of inert balls made of Leucite extrapleurally inside the chest. These collapse the underlying lung. Plombage was a surgical therapy for TB used before antibiotic therapy was available. Other surgical treatments included crushing of the phrenic nerve (which leaves a small supraclavicular scar and a raised hemidiaphragm on the treated side) and thoracoplasty, in which the ribs over the upper lobe were removed. All these treatments collapsed the underlying lung and controlled TB by making the affected lobe underventilated and therefore hypoxic (as Mycobacterium tuberculosis requires aerobic conditions to grow). Antituberculous chemotherapy now means these operations are generally obsolete, although thoracoplasty may very rarely be used to control highly drug-resistant TB. Nowadays, the main relevance of these surgical treatments are the long-term complications. Thoracoplasty causes a restrictive lung function impairment which can lead to type 2 respiratory failure that responds well to chronic nocturnal non-invasive ventilation, and plombage can become infected or cause pressure effects on local structures.
