A 55-year-old woman from the Southeastern US with a history of smoking, poorly controlled type 2 diabetes mellitus (hemoglobin A1c level, 15.5%), and chronic pain from osteoarthritis treated with inhalational medical marijuana presented with 4 months of productive cough, 22.7-kg (50-lb) weight loss, subjective fevers, and 3 days of worsening chest pain.
Chest computed tomography (CT) showed a large right upper lobe cavitary mass. She was treated empirically with intravenous vancomycin and piperacillin-tazobactam. Bronchoscopy with bronchoalveolar lavage (BAL) and transbronchial biopsy was performed. Lung tissue was sent for bacterial, fungal, mycobacterial, and Nocardia cultures and for histopathology. BAL cultures grew 100 colony-forming units (CFUs)/mL of group B streptococci and 1 CFU/mL of Aspergillus niger. Results of acid-fast bacilli (AFB) smear and GeneXpert MTB/RIF testing were negative. Voriconazole was added to her treatment. Transbronchial biopsy histopathology showed acute and chronic inflammation, granulation tissue and necrosis, and negative fungal and AFB stains.
