Core Tip

Core Tip: Patients with CD4+ T-cell deficiency should be aware of Nocardia infection. Nocardia pneumonia shares similar imaging and clinical features with pulmonary tuberculosis and lung neoplasms, but the treatment and anti-infective medication are completely different. Here, we report a case of pulmonary nocardiosis caused by Nocardia cyriacigeorgica (N. cyriacigeorgica), which was misdiagnosed as community-acquired pneumonia with repeated fever. We identified the pathogen by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The patient used compound sulfamethoxazole tablets (0.96 g) three times a day. After one week of treatment, the infection index returned to normal, the patient's condition improved significantly, and she was discharged.
