| 目的 分析肺撕裂伤的CT特征并探讨其分型。方法 回顾性分析22例肺撕裂伤的CT表现。结果 22例肺撕裂伤患者累及32侧,共54个病灶,大多数位于肺的背部,靠近或紧贴胸膜,可单发或多发。CT表现为高密度的肺内血肿,含气囊腔或液气囊腔。"银环征"及 "杯中乳液征" 为肺撕裂伤的特征性表现。结论 螺旋CT检查可早期显示肺撕裂伤,其诊断价值明显优于传统X线检查。 |

| Objective To evaluate CT features of pulmonary laceration and discuss its classification. Methods CT appearance of twenty-two patients with pulmonary laceration were analyzed retrospectively. Results Of 22 patients, pulmonary lacerations involved 32 sides (54 lesions in total), the site of laceration most located in the back of the lung and near the pleura, single or multiple in number. CT appearance presented as pulmonary hematomas (11/54), cavitary lesions with air-fluid levels (35/54), cavitary lesions with air (8/54). 'Silvery ring sign' and 'intracup milk sign' are characteristics. Conclusion Spiral CT may detects pulmonary laceration early, it is superior to traditional X-ray examination in the diagnosis of pulmonary laceration. |
