Imaging findings
Chest radiograph shows numerous cystic and large cavitary spaces with associated architectural distortion. CT imaging reveals extensive cystic bronchiectasis, large cavities, and tree-in-bud opacities, a pattern often associated with drug-resistant tuberculosis. Subsequent scans showed progression with increased consolidation and nodular disease, indicative of a highly destructive process.
Key takeaways
This case demonstrates another aggressive and destructive presentation of Mycobacterium Avium Complex (MAC) infection in a male patient, characterized by widespread cystic bronchiectasis, large cavitary lesions, and tree-in-bud opacities. The severe lung destruction mimics features of drug-resistant tuberculosis, underscoring the potential for MAC to cause profound parenchymal damage, particularly in non-typical patient demographics.
