骨化性气管支气管病的CT诊断

目的 探讨骨化性气管支气管病的CT特征，提高对该病的认识。方法 回顾分析6例经病理证实的骨化性气管支气管病的CT表现。结果 CT主要表现为气管、主支气管前壁和侧壁黏膜下散在或多发的斑块状小结节突起，突向管腔，部分结节钙化，大多数小结节直径在2～4mm，有2例在叶支气管可见；2例同时出现气管壁增厚，气管环变形，管腔狭窄。结论 气管、主支气管内多发的黏膜下小结节钙化影并突向管腔是骨化性气管支气管病较具特征性的CT表现。

Diagnosis of tracheobronchopathia osteochondroplastica by computed tomography

Objective To study the CT features and enhance the knowledge of tracheobronchopathia osteochondroplastica (TO). Methods The CT appearances in 6 patients with pathologically proved TO were analyzed retrospectively. Results CT of the chest revealed scattered and multiple mural nodules protruding into the tracheobronchial lumen. Punctate calcification occurred within these nodules. The nodular lesions usually involved the anterior and lateral walls of the trachea and major bronchi. These nodules generally ranged from 2 to 4 mm in diameter. The nodular lesions were seen on lobar bronchi in two cases. Diffuse irregular mural thickening of the trachea and deformed tracheal cartilage rings were observed in two cases. Conclusion CT demonstration of multiple mural nodules with calcification in the tracheobronchial tree is a characteristic finding for TO.
