Imaging findings
Numerous diffuse lung nodules demonstrate a miliary pattern, with individual nodules appearing slightly larger than typically seen in tuberculosis or histoplasmosis. Older CT scans also show subtle necrosis within enlarged lymph nodes, which can be a distinguishing feature from miliary tuberculosis. The disease persisted over several months across multiple scans.
Key takeaways
This case illustrates disseminated Coccidioidomycosis, often seen in immunosuppressed patients, characterized by diffuse miliary lung nodules that can be larger than other granulomatous infections. The presence of necrotic lymphadenopathy is a valuable imaging clue. This highlights the chronic and widespread nature that coccidioidomycosis can adopt, especially in susceptible individuals.
