BACKGROUND: Nocardia infection is an emerging concern in solid organ recipients due to prolonged immunosuppression.
CASE PRESENTATION: We report the case of a 45-year-old woman with a history of cystic fibrosis who underwent bilateral lung transplantation. Eight years posttransplant, she developed progressive respiratory symptoms. Imaging revealed cavitary nodular lesions, and Nocardia cyriacigeorgica was isolated from bronchoalveolar lavage and sputum cultures. Treatment with meropenem and trimethoprim-sulfamethoxazole led to clinical and radiological improvement.
CONCLUSION: This case highlights the diagnostic challenges of Nocardia infections, the importance of microbiological interpretation, and the potential for late-onset disease in transplant recipients despite prophylaxis. Awareness of Nocardia as an opportunistic pathogen is crucial for timely diagnosis and management. Our findings underscore the need for continued vigilance in solid organ transplant recipients, particularly in cases of persistent pulmonary infections and high immunosuppressive therapy.
