骨化性气管支气管病的CT诊断并文献复习

Diagnosis of tracheobronchopathia osteochondroplastica by computed tomography and literature review

目的探讨并总结骨化性气管支气管病(TO)的病史及临床特点,CT特征,降低CT诊断的漏诊及误诊率,提高对该病的认识。方法报道1例经病理证实的TO患者,结合其临床及CT表现,并复习相关文献,总结TO的CT诊断。结果共总结国内42例TO患者的CT表现,其主要表现为:气管及支气管前壁、侧壁(后壁通常不受累)多发增生性散在或多发结节突向管腔,部分甚至钙化。结论高分辨率CT(HRCT)薄层扫描作为一种重要非侵入性诊断方法在确诊疑似TO患者时具有高灵敏性,应受到重视。

Aim To explore and summarize the disease history,clinical and CT features of tracheobronchopathia osteochondroplastica（TO）,to reduce the rate of missed diagnosis and misdiagnosis,and to raise the recognition of TO.Methods Report of one new cased with pathologically proved TO and 41 cases in the Chinese medical literature were reviewed.Results The CT-scan disclosed the abnormal presence of cartilage and bone tissue in the bronchial submucosa.It revealed scattered and multiple mural nodules protruding into the tracheobronchial lumen.Hard sessile nodules arose from the anterior and lateral walls of the airway,typically sparing the posterior membrane,which played an important role in the diagnosis of TO.Conclusion High-resolution CT（HRCT）scans as an important non-invasive diagnostic methods in diagnosis of suspected TO patients have a high sensitivity.
