CTICasesBlastomycosis
Imaging findings
Chest CT shows a rapidly progressive right upper lobe mass-like consolidation, centrilobular nodules, a small pleural effusion, and no significant lymphadenopathy. Bronchoalveolar lavage smear showed large, broad-based budding yeast.
Key takeaways
Pulmonary blastomycosis can present as a rapidly growing mass-like lung consolidation that mimics lung cancer. Unlike histoplasmosis or tuberculosis, it typically lacks significant hilar/mediastinal lymphadenopathy and has a higher association with small pleural effusions.
