Abstract: 【Abstract】Objectives To investigate clinical features of polyserositis caused by co—infection，causes of misdiagnosis and propose preventive measures．Methods Retrospective analysis of clinical data from one case of polyserositis in our hospital caused by CO—infection of tuberculosis and mycoplasmal pneumonia． Results The child was admitted in our hospital because of cough，abdominal distension for more than 1 month．The early course of the disease was diagnosed as pneumonia in another hospital before our diagnosis of myeoplasmal infection．After giving the appropriate treatment，we found that cough disappeared，perieardial effusion and pyoperitoneum absorbed，but the right pleural effusion existed．We stopped the treatment and then a small amount of pyoperitoneum and pleural effusion was increased．Serum T—Spot．TB antigen showed positive．Considering tuberculosis and using soniazid，rifampicin and pyrazinamide as anti—TB treatment for 3 weeks，right pleural effusion was not significantly absorbed．After prednisone 2 mg／(kg’d)orally was added for 10 d，chest X ray showed that pleural effusion was absorbed，suppofling the diagnosis of tuberculosis． Conclusion Atypical history and signs，single negative culture for tubercle bacillus in pleural effusion and normal ADA and T—Spot．TB concentration in pleural effusion are the main causes of misdiagnosis．Repeating examination of pleural fluid and blood ADA and T-Spot．TB concentration may help in confirming the diagnosis．
