Diagnosis With Brief Discussion
- Diagnosis
- Mycobacterium infection other than tuberculosis (M. avium-intracellulare)
- Radiologic Findings
- Initial chest radiograph shows multiple poorly-defined nodules in both lower lung zones. HRCT scans demonstrate multiple poorly-defined nodules and masses that show cavity and surrounding ground-glass attenuation halo. Contrast-enhanced CT scan shows ill-defined areas of low-attenuation in the nodules and masses.
Follow-up chest radiograph 4 days later shows markedly increased sizes of the nodules and masses. AFB was demonstrated on bronchoalveolar lavage fluid and sputum culture revealed nontuberculous mycobacterium (M. avium-intracellulare).
