Case report reveals successful targeted combination therapy for severe Nocardia farcinica necrotizing pneumonia in an immunocompetent host, highlighting the importance of rapid MALDI-TOF diagnosis.

Key Points

To report a rare case of severe necrotizing pneumonia caused by multidrug-resistant Nocardia farcinica in an immunocompetent patient and describe its successful diagnostic and therapeutic management.
Evaluated a 74-year-old immunocompetent woman presenting with a 20-day history of fever, productive cough, and altered mental status (GCS 9 to 12).
Diagnosed the causative organism via endotracheal aspirate culture identified with MALDI-TOF mass spectrometry 6 to 7 days after admission.
Administered targeted combination therapy with intravenous imipenem-cilastatin, intravenous amikacin, and oral trimethoprim-sulfamethoxazole (TMP-SMX).
MALDI-TOF analysis confirmed necrotizing pulmonary infection caused by multidrug-resistant Nocardia farcinica.
Targeted triple antimicrobial therapy led to complete clinical, neurological, and radiological resolution at 6 months of follow-up.
