CTICasesPulmonary Blastomycosis
Imaging findings
CT chest shows a solid, focal mass-like consolidation in the right upper lobe, mimicking bronchogenic carcinoma, with a complete absence of hilar or mediastinal lymphadenopathy.
Key takeaways
Blastomycosis is a dimorphic fungus endemic to the Great Lakes and Mississippi River regions. In the lungs, it frequently presents as a mass-like consolidation that mimics lung cancer. Unlike histoplasmosis or coccidioidomycosis, blastomycosis typically does not cause significant mediastinal lymphadenopathy.
