To investigate the chest CT manifestations of paragonimiasis at different clinical phases.
Forty-eight cases of paragonimiasis confirmed by laboratory studies were retrospectively analyzed. There were 30 males and e18 females ageing 9 - 66 years (average, 31.4 years). Conventional chest CT was performed in all cases and contrast enhanced CT in some cases.
The chest CT findings of paragonimiasis included: (1) peribronchial inflammation (n = 9); (2) infiltration (n = 13), manifested as unilateral or bilateral patchy infiltrates with hazy borders. The location and shape were variable. The typical "canal gas-path" sign was seen in a few patients; (3) nodular and masses (n = 11); (4) cysts and cavity (n = 6); (5) pleural effusion (n = 9). The CT appearances of paragonimiasis were different at different clinical phases. Peribronchial inflammation, infiltration and pleural effusion were early presentations, not distinguishable from other common infections. The appearance of nodules, masses, cysts and cavities was more common in the clinical course. At the stabilization phase, nodular cavity or pleura thickening and calcification were revealed.
There are various abnormalities on chest CT at different phases of paragonimiasis. Combination of clinical manifestations with chest CT characteristics is important in the diagnosis of paragonimiasis.
探讨并殖吸虫病不同临床阶段的胸部CT表现。
回顾性分析48例经实验室检查确诊的并殖吸虫病患者。其中男性30例，女性18例，年龄9 - 66岁（平均31.4岁）。所有患者均行胸部常规CT检查，部分患者行增强CT检查。
并殖吸虫病的胸部CT表现包括：（1）支气管周围炎症（9例）；（2）浸润（13例），表现为单侧或双侧边界模糊的斑片状浸润影，位置及形态各异，少数患者可见典型的“隧道气路”征；（3）结节及肿块（11例）；（4）囊肿及空洞（6例）；（5）胸腔积液（9例）。并殖吸虫病在不同临床阶段的CT表现不同。支气管周围炎症、浸润及胸腔积液为早期表现，与其他常见感染难以鉴别。结节、肿块、囊肿及空洞在病程中更为常见。在稳定期，可见结节状空洞或胸膜增厚及钙化。
并殖吸虫病不同阶段胸部CT有多种异常表现。结合临床表现及胸部CT特征对并殖吸虫病的诊断具有重要意义。
