CTICasesCoccidioidomycosis
Imaging findings
Chest CT shows a peripheral area of necrotic consolidation with surrounding ground-glass opacity, septal thickening, and tiny satellite nodules in the right lower lobe, which remained stable over a year and a half after treatment. Sputum cultures confirmed disseminated coccidioidomycosis.
Key takeaways
Coccidioidomycosis is a fungal infection endemic to the southwestern United States, acquired by inhaling arthroconidia from dust. It can present as a necrotic pulmonary nodule or consolidation with satellite nodules, and dissemination can lead to chronic meningitis.
