Isolation lung cysticercosis reports are rare in literature. Most lung lesions were characterized by nodules. The investigators access one case which was characterized with pulmonary cavity and pleural effusion by Gupta N, et al in 2015 from PUBMED and Medline. But pleural effusion and exudative lesions is reported for the first time.

Cysticercosis is an important public health problem in developing countries. The major involvement sites are the central nervous system and the eyes，although striated muscles and subcutaneous tissues are frequently involved in the disseminated form of disease. Pulmonary involvement in cysticercosis is very rare and ill-defined nodular shadows distributed throughout the lung is the usual radiological presentation. Only one case of cysticercosis presenting as lung cavity with pleural effusion has been reported so far in literature. The investigators describe two cases in which pleural effusion due to cysticercosis were detected on X and CT.

Inclusion Criteria:

1. Clinical diagnosis of Pulmonary Cysticercosis。
2. With pleural effusion

Exclusion Criteria:

1.No cysticercosis was found by biopsy or antibody test

Two patients with pleural effusion presenting with chest tightness and chest pain were enrolled in this study with a definitive diagnosis of cysticercosis confirmed by pleural effusion examination
