CTICasesStenotrophomonas maltophilia pneumonia in an immunocompromised host
Imaging findings
CT chest shows rapidly progressive, dense right upper lobe consolidation with prominent air broncograms and surrounding ground-glass opacity in a stem-cell transplant recipient.
Key takeaways
Stenotrophomonas maltophilia is an opportunistic gram-negative bacillus that causes severe pneumonia in immunocompromised patients. The presence of prominent air broncograms on CT points toward a bacterial cause, helping differentiate it from angioinvasive fungal infections like Mucor or Aspergillus.
