Objective To analyze the clinical characteristics or differential diagnosis of extravasated pleural effusion.Methods Clinical data of inpatients suffered from extravasated pleural effusion (EBE) from March 2003 to December 2004 were collected. Respective analysis was carried out on the clinical manifestations, differential diagnosis, or treatment of PE.Results EPE was mainly resulted from tuberculosis. The rate of malignant pleural effusion (MPE) was second to the tuberculous pleural effusion (TPE). The least occurrence to PE was suffered from paragonimiasis. TPE mostly occurred at either pleural cavity. No significant difference between right and left was found. But PE was frequent at both the two pleural cavities. The TPE or MPE was characteristic of extravasate. The smear positive rate of tuberculous bacterium from the PE was not high. Bloody effusion was often found from MPE and malignant cell was easily found from the samples. It was effective by anti-tuberculous treatment on TPE. The primary or matastatic foci were often found in the lung or jugular lymph node. PE suffered from paragonimiasis may be little sticky and the colour of coffee. It was hard to detect the parasites, but easy to assay positive seral antibody. Conclusion The most pathogens resulted in PE is tuberculous bacteria. PE suffered from either malignant tumor or parasitosis should be considerably suspected when anti-tuberculous treatment brings no effect. It is necessary to diagnose the MPE by X-ray test, computerized tomography, or biopsy of jugular lymph nodes. Efficient chemotherapeutic program should be adopted so as to lessen the MPE and reduce the bad affect on the body. PE accompanied by parasitosis could be diagnosed with seroimmunological assay for the seral antibody.
