KROK 1 2015 – Question 28 · KROK (Medicine) · Pathomorphology
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 of tuberculous granulation tissue and the external one was made of connective tissue. What is the most likely diagnosis?
- A. Fibrous focal tuberculosis
- B. Acute focal tuberculosis
- C. Tuberculoma
- D. Acute cavernous tuberculosis
- E. Fibrous cavernous tuberculosis
Hint
Consider how the structure of the cavity wall changes as cavitary tuberculosis becomes chronic, and what the outermost layer tells you.
