| 目的 观察支气管色素沉着纤维化（BAF）致肺不张的CT表现。方法 回顾性分析86例经支气管镜、病理或临床随访诊断的BAF致肺不张胸部CT表现，观察肺不张分布、形态、强化特点，以及肺内伴随征象、纵隔淋巴结改变及肺外改变。结果 86例中，51例（51/86，59.30%）见单发肺不张，35例（35/86，40.70%）见多发肺不张，共127个肺不张病灶；位于右肺中叶47个（47/127，37.01%），右肺上叶31个（31/127，24.41%），左肺上叶28个（28/127，22.05%），双肺下叶21个（21/127，16.54%）；85个（85/127，66.93%）呈扇形伴支气管黏液嵌塞或斑片状低强化，42个（42/127，33.07%）呈非扇形伴或不伴空气支气管征。66例（66/86，76.74%）见结核相关病变；86例（86/86，100%）均见不同程度肺间质性病变、小气道病变及纵隔、肺门淋巴结肿大融合伴钙化致邻近支气管、血管狭窄或闭塞；肿大淋巴结平扫CT密度（62.21±21.87） HU，增强后可见均匀强化（68/86，79.07%）及环形强化（18/86，20.93%）。64例（64/86，74.42%）存在肺外改变，包括患侧胸腔积液、膈肌抬高、胸廓略塌陷及纵隔移位。结论 BAF致肺不张CT表现具有一定特征性。 |

| Objective To observe CT manifestations of atelectasis caused by bronchial anthracofibrosis (BAF). Methods Totally 86 patients with atelectasis due to BAF diagnosed with bronchoscopy, pathology or clinical follow-up were enrolled, and CT manifestations were retrospectively reviewed. The distribution, morphology and enhancement of atelectasis, the accompanied signs in the lung, the changes of mediastinal lymph nodes and extrapulmonary were observed. Results Single atelectasis was observed in 51 cases (51/86, 59.30%), while multiple atelectasis were found in 35 cases (35/86, 40.70%). A total of 127 atelectasis lesions were detected, 47 (47/127, 37.01%) in the right middle lobe, 31 (31/127, 24.41%) in the right upper lobe, 28 (28/127, 22.05%) in the left upper lobe and 21 (21/127, 16.54%) in the lower lobe of both lungs. Fan shape with bronchial mucoid impaction or patchy low enhancement was observed in 85 lesions (85/127, 66.93%), while non-fan shape with or without air bronchogram sign were observed in 42 lesions (42/127, 33.07%). Pulmonary interstitial lesions and small airway lesions were detected in all 86 cases (86/86, 100%) with mediastinal and/or hilar lymph nodes enlarged and fused calcifications, resulting stenosis or occlusion of the adjacent bronchi and blood vessels, while tuberculosis related lesions were noticed in 66 cases (66/86, 76.74%). CT value the enlarged lymph node was (62.21±21.87) HU on plain scanning, while homogeneous and annular enhancement was found in 68 (68/86, 79.07%) and 18 cases (18/86, 20.93%), respectively. Extrapulmonary changes, including pleural effusion, diaphragm elevation and slightly collapsed thorax on the affected side, as well as mediastinal displacement were found in 64 cases (64/86, 74.42%). Conclusion CT manifestations of atelectasis caused by BAF had certain characteristics. |
