Explanation

Autopsy of a man who had tuberculosis revealed a 3x2 cm large cavity in the superior lobe of the right lung. The cavity was interconnected with a bronchus, its wall was dense and consisted of three layers: the internal layer was pyogenic, the middle layer was made by tuberculous granulation tissue and the external one was made by connective tissue. What is the most likely diagnosis? Fibrous cavernous tuberculosis is normally found in the superior lobe of lungs, fibrous meaning there is the formation of connective tissue, Cavernous meaning there is the formation of a cavity and of tuberculous origin.
