CTICasesDisseminated Mycobacterium bovis Infection
Imaging findings
A chest radiograph and CT scan in a young female patient demonstrate innumerable fine, diffuse miliary nodules with lower-lung predominance, along with calcified cavitary lesions in the upper lobes.
Key takeaways
Mycobacterium bovis is a member of the Mycobacterium tuberculosis complex that typically causes bovine tuberculosis but can infect humans, historically through the consumption of unpasteurized milk or raw cheese. M. bovis is naturally resistant to pyrazinamide, making accurate speciation crucial for selecting the appropriate anti-mycobacterial regimen.
