摘　　要：目的　探讨并殖吸虫病不同临床时期的胸部CT表现。方法　对 5 0例经临床证实的并殖吸虫病胸部CT所见进行回顾性分析 ,并着重就其CT所见进行探讨。结果　并殖吸虫病的胸部CT表现可分成 5类 ,浸润性改变 15例 ,支气管周围炎样改变 12例 ,囊肿阴影 11例 ,附壁结节空腔8例 ,胸腔积液 4例。并殖吸虫病在不同的时期出现不同的胸部CT表现 ,浸润性和支气管周围炎样改变以及胸腔积液是感染的早期表现 ;囊肿出现是中期的表现 ;稳定后期表现为附壁结节空腔或胸膜增厚、钙化。附壁结节空腔内“瓜子”状附壁结节影 ,或在浸润灶中出现与支气管走形不一致的“隧道征”影 ,对并殖吸虫病有一定的提示诊断意义。结论　并殖吸虫病的不同时期 ,胸部CT均可发现异常改变。Objective To investigate the chest CT manifestations of paragonimiasis at different clinical periods.Methods CT findings in 50 cases of clinically confirmed paragonimiasis were retrospectively analyzed,and CT presentation was emphasized.Results The chest CT presentation of paragonimiasis may be divided into 5 kinds: infiltration (n=15),inflammation around bronchia (n=12),cyst (n=11),wall-node cavity (n=8),and pleural effusion (n=4).CT appearances of paragonimiasis were different at different clinical phase.The infiltration,inflammation around bronchia,and pleural effusion were early presentations,not distinguishable from common infections.The appearance of cyst was detected at the medium-term.At stabilization phase,wall-node cavity or pleura incrassation and calcification were revealed.The 'melon seed' node inside the wall-node cavity and 'canal gas-path' in soakage shadow were significant clue to the diagnosis of paragonimiasis.Conclusion There are various abnormalities on chest CT at different paragonimiasis periods.
