目的探讨多层螺旋CT三维重组技术在气管支气管非肿瘤性少见病变的临床应用价值。方法回顾性分析16例经支气管纤维镜活检病理确诊为气管支气管非肿瘤性少见病变,行多层螺旋CT扫描,所有数据发送至重建工作站进行三维重建。结果 16例病例中,气管支气管淀粉样变6例,男女各3例,中位年龄51岁;骨化性气管支气管病4例,男3例,女1例,中位年龄25岁;气管支气管复发性多发性软骨炎6例,男2例,女4例,中位年龄48岁;在CT多平面重建工作站重建后可清楚显示,气管支气管淀粉样变显示病变主要以管壁增厚钙化为主,病变呈连续性,管壁钙化以支气管明显,管腔明显狭窄;骨化性气管支气管病变显示气管前壁及两侧管壁增厚及结节样钙化影突入管腔内,钙化主要位于粘膜上并突入气管支气管管腔内,管腔狭窄不明显;气管支气管复发性多发性软骨炎以气道多发炎性水肿增厚为主,管腔可见明显连续性狭窄,管壁可见小点状钙化,管壁内侧相对光滑,病变多数弥漫,以气管病变明显;继发肺部阻塞性炎症9例,气管支气管淀粉样变5例,气管支气管复发性多发性软骨炎3例,骨化性气管支气管病1例。结论多层螺旋CT三维重建技术在大气道非肿瘤性少见病变中可直观、多方位观察管壁、管腔情况,为临床诊断提供更多的可靠信息。
Objective To explore the clinical value of MSCT three-dimensional reconstruction technique in rare non-neo- plastic lesions of trachea and bronchi. Methods Sixteen cases diagnosed as rare non-neoplastic lesions of trachea and bronchi by pathology after bronchial fiberscope biopsy were retrospectively analyzed. All patients underwent CT scan and then the data were transferred to three-dimensional reconstruction workstation. Results In this work, there were six cases of tracheobronchial amyloidosis, including three males and three females, with a median age of 51 years; there were four cases of tracheobroncheopathia steochondroplastiesa, including three males and one female, with a median age of 25 years; and there were six cases of relapsing polychondritis, including two males and four females, with a median age of 48 years. The computer tomography three-dimensional reconstruction clearlyshowed that tracheobronchial amyloidosis presented with wall thickening and calcification, continuous lesions, significant calcification of bronchial wall, and significant lumen stenosis. The tracheobroncheopathia steochondroplastiesa showed that both sides and anterior wall appeared thickening and nodular calcification of the trachea, calcified nodules mainly in the mucosa and broke into the lumen, but, lumen stenosis was not obvious. The relapsing polychondritis showed airway inflammatory edema and thickening, lumen stenosis, small punctate calcification in wall, relative smooth inner wall, diffused lesions, and obvious lesions in the trachea. There were nine cases secondary to obstructive lung inflammation, five of tracheobronchial amyloidosis, three of relapsing polychondriti, and one tracheobroncheopathia steochondroplastiesa. Conclusion MSCT three-dimensional reconstruction technique can provide intuitive and multi-dimensional observation of the wall and the lumen, as well as more reliable information for the clinical diagnosis of rare non-neoplastic airway diseases.
