肺内支气管囊肿的CT表现

目的 探讨肺内支气管囊肿的CT表现特点。方法 回顾性分析57例经手术病理证实的支气管囊肿的CT表现。结果 57例肺内支气管囊肿,48例发生于单叶肺,3例累及一侧多叶肺,6例累及双肺多叶。21例CT表现为球灶型,19例呈空腔型,8例呈肿块样型,9例呈蜂窝型。13例含有曲菌球,5例囊壁发生钙化。15例见囊肿周围透亮度增高影,24例见周围条状实变影,4例见邻近肺组织节段性压缩不张,9例见近端引流支气管扩张积液。结论 大部分肺内支气管囊肿的CT表现具有特征性,有助于术前诊断。

CT manifestations of pulmonary bronchogenic cysts

Objective To investigate CT manifestations of congenital pulmonary bronchogenic cysts. Methods CT features of 57 patients with pulmonary congenital bronchial cysts confirmed by pathology after operation were reviewed retrospectively. Results The lesions located in single lobe in 48 patients, in multi lobes of single lung in 3, and multi lobes of bilateral lungs in 6 patients. Pulmonary nodular opacity was detected in 21 patients, air-filled cyst in 19 patients, irregular mass attenuation in 8 patients and honeycomb-like cyst in 9 patients. Aspergilloma was seen in 13 patients. Spotty or curved calcification of the cystic wall was found in 5 patients. Pericystic emphysema and bandlike linear attenuation presented in 15 and 24 patients, respectively. Segmental pulmonary atelectasis by mass effect was seen in 4 patients, while proximal bronchiectasis and hydrops in 9 patients. Conclusion Most congenital pulmonary bronchogenic cysts show characteristic CT signs, which are helpful to preoperative diagnosis.
