A Case Report of Disseminated Nocardiosis

Objective: To summarize the clinical characteristics and treatment plan for a case of disseminated nocardiosis. Methods: The study summarized the clinical characteristics and treatment plan for a case of disseminated nocardiosis. Results: The primary symptoms of the patient included high fever and multiple enlarged lymph nodes. Chest computed tomography revealed a shadow of nodules in the upper lobe of the left lung, multiple nodules, and pleural effusion in both lungs. Additionally, bilateral blood cultures indicated the presence of Nocardia terpenica. The final diagnosis was disseminated Nocardia sp. infection. Upon admission, anti-infective treatment was initiated with sulfamethoxazole and linezolid. Conclusion: In patients with normal immune function, disseminated nocardiosis may present as high fever with lymph node enlargement, necessitating differentiation from lymphoma. This study reports on the diagnosis and treatment plan of a case of disseminated nocardiosis to enhance understanding and clinical management of this disease.
