Summary
A rare case of adult nontuberculous mycobacterial (NTB) infection caused by methicillin-resistant Staphylococcus aureus (MRSA) led to fatal airway obstruction. This highlights the critical need for prompt diagnosis and management of severe NTB in adults.
Area of Science:
- Pulmonary Medicine
- Infectious Diseases
- Critical Care
Background:
- Nontuberculous mycobacterial (NTB) infections are uncommon in adults, particularly those without mechanical ventilation.
- Severe airway compromise due to NTB is exceptionally rare.
Observation:
- A 56-year-old man presented with hemoptysis and dyspnea, exhibiting decreased breath sounds and rhonchi.
- Imaging revealed bilateral lower lobe infiltrates; bronchofiberscopy showed tracheal and bronchial mucosal necrosis and hemorrhage.
- Methicillin-resistant Staphylococcus aureus (MRSA) was identified in respiratory samples.
Findings:
- The patient was diagnosed with NTB caused by MRSA.
- Despite medical intervention, the patient succumbed to airway obstruction by necrotic tissue on the 7th hospital day.
- Autopsy confirmed the cause of death.
Implications:
- This case underscores the potential for severe, life-threatening airway complications in adult NTB, even without prior ventilation.
- Early recognition and aggressive management are crucial for improving outcomes in such rare but severe presentations.
- Highlights MRSA as a potential pathogen in severe pulmonary infections mimicking or coexisting with NTB.
