CTICasesDisseminated Blastomycosis presenting as knee synovitis and osteomyelitis
Imaging findings
Knee MRI shows complex joint effusion, synovitis, and bone erosion with adjacent bone marrow edema. Chest CT shows asymptomatic, scattered bilateral pulmonary nodules (2-3 mm).
Key takeaways
Disseminated Blastomycosis can present as a destructive skeletal lesion or joint mass that mimics sarcoma. Pulmonary involvement may be asymptomatic and manifest as subtle, small nodules, which should raise suspicion in endemic areas.
