| 【】 目的 探讨局限性气管支气管淀粉样变性的CT平扫表现特点及其诊断价值,以提高其认识水平。方法 回顾性分析7例经病理证实的局限性气管支气管淀粉样变性患者的临床及CT平扫表现及伴随征象,其中男5例,女2例,年龄平均48岁(32~69岁)。7例均行胸部CT平扫。7例均经病理组织学检查示淀粉样变性。结果 7例气管壁弥漫增厚伴管腔不同程度狭窄,7例气管均无软化,气管粘膜下斑块3例呈环形分布,4例呈不均匀分布,4例中2例以气管前壁分布为著,4例中1例以右侧壁分布为著,4例中1例以前壁及两侧壁分布为著；4例累及两侧主支气管,1例累及左上叶支气管伴管腔狭窄,1例未累及支气管,1例累及两侧主支气管及广泛分支伴管腔不同程度狭窄、扩张；2例可见气管腔内软组织结节；2例伴随肺部并发症,其中1例伴随左下肺不张,另1例伴随两肺弥漫支气管狭窄、扩张。7例均行病理组织学检查示淀粉样变性。结论 局限性气管支气管淀粉样变性CT平扫表现具有一定的特征性,并可发现肺部并发症,对疾病的诊断治疗有一定的指导作用。 |

| Abstract: |
| Objective To investgate the CT scan features of tracheobronchial amyloidosis in order to improve the diagnosis.Methods CT imagings of 7 patients(5 males and 2 females, mean age 48,range from 32~69 years.)with tracheobronchial amyloidosis histopathologically confirmed retrospectively analyzed.7 patients performed CT scan of thorax.Results 7 patients were diffuse lesions in tracheobronchial tree with wall thickening and lumen stenosis unequally.3/7 manifest annular wallthickening,4/7 manifest nonuniform wallthickening, 2/4 involve the front wall distinctly,1/4 involves the right wall distinctly,1/4 involves the front and two sides of the walls distinctly.4/7 involve two sides of the main bronchuses.1/7 involve the upper left lobe bronchus.1/7 involve the main bronchuses and all branches.1/7 uninvolved.2/7 find a soft tissue nodule against to the wall respectively.2/7 accompanied by applications,such as pulmonary atelectasis,diffuse bronchiectasia.7 patients performed histopathological examinations result of amyloidosis. conclusion tracheobronchial amyloidosis has certain characteristic on CT scan,this examination can help find applications of the lung,and plays a guidance role in diagnosis and treatment. |
