Imaging findings
CT shows multifocal consolidations with small cavitations in a young male from northern Wisconsin, associated with a tiny pleural effusion and mild reactive lymphadenopathy, demonstrating budding yeast on fungal smear.
Key takeaways
Blastomycosis is an endemic fungal infection that can mimic tuberculosis or malignancy on CT. Key clues include geographic exposure, lack of response to standard antibiotics, and the presence of only a tiny pleural effusion and mild non-necrotic lymphadenopathy.
