闭塞性细支气管炎伴机化性肺炎的高分辨CT表现

High-resolution CT Findings in Bronchiolitis Obliterans with Organizing Pneumonia

目的探讨闭塞性细支气管炎伴机化性肺炎的高分辨CT表现,并与慢性嗜酸性肺炎和寻常型间质性肺炎进行鉴别。方法结合相关文献回顾性分析12例闭塞性细支气管炎伴机化性肺炎高分辨CT表现。结果12例闭塞性细支气管炎伴机化性肺炎的高分辨CT表现如下:(1)肺内多发斑片状肺实变影和磨玻璃影(n=8),其中肺实变影中见支气管充气征(n=5)。(2)肺内多发小结节影和不规则线状影(n=7)。(3)肺内多发斑片状肺实变影和磨玻璃影伴小结节影和不规则线状影(n=3)。(4)细支气管扩张、壁增厚伴周围肺实变影(n=6)。(5)肺内肺实变影和磨玻璃影呈游走性(n=3)。结论高分辨CT可以更好地显示闭塞性细支气管炎伴机化性肺炎的病理改变,并使其能与慢性嗜酸性肺炎和寻常型间质性肺炎在影像上进行鉴别,也为纤维支气管镜下肺活检提供准确的定位。

Objective To review the high-resolution computerized tomogvaphy （ CT） findings of bronchiolitis oblitemns with organizing pneumonia （BOOP） and to differentiate BOOP from citronic eosinophilie pneumonia （CEP） and usual interstitial pneumonia （UIP）. Methods The high-resolution CT findings of BOOP in 12 eases were retrospectively analyzed and the relative articles were reviewed. Results The high-resolution CT findings of 12 cases of BOOP were as following： patchy air-space cone.olidation and ground glass attenuations （ n = 8） , air-brnnchogram in air-space consolidation （ n = 5 ） , small nodular opacities and irregular linear opacities （rt = 7 ）, patchy air-spac：e （：onsolidation and ground glass attenuation with nodular and irregldar linear opacities （n=3） , bronehial wall thickening and dilatation with air-space opaeities （ n = 6） , imaging of air-spacc consolidation and ground-glass attenuation （ n = 3 ）. Conclusion The pathological changes of BOOP can be well shown by high-resolution CT and the differential diagnosis between BOOP and CEP or UIP can be made, too. The high-resnlution CT can act as a guide to select thc optimal biopsy sites in the padents with BOOP.
