幼年型喉乳头状瘤支气管及肺内播散的CT表现

CT findings of juvenile laryngeal papilloma spreading in bronchia and lung

目的:探讨幼年型喉乳头状瘤支气管及肺内播散的CT表现。方法:回顾性分析7例经手术病理证实的幼年型喉乳头状瘤患儿支气管及肺内播散的CT表现。7例患儿均经多层螺旋CT平扫检查,有3例做CT增强扫描,2例做MPR重建,观察其CT特征。结果:7例幼年型喉乳头状瘤支气管及肺内播散的患儿,CT表现为双肺散在、多发大小不等含气囊腔及结节影,沿气道分布于肺部中心和外周,结节呈均匀软组织密度或液体密度;含气囊腔多为单囊,囊壁可为薄壁,也可为厚壁,以薄壁为主,大部分囊壁光整,部分囊腔与支气管相通,较少并发肺部炎症。结论:多层螺旋CT扫描能反映幼年型喉乳头状瘤支气管及肺内播散的CT表现特点,具有一定的特征性,有助于提高该病的诊断准确性。

Objective：To investigate the imaging findings of juvenile laryngeal papilloma spreading in the bronchia and lung with spiral CT.Method：Seven cases of juvenile laryngeal papilloma spreading in bronchia and lung were collected.All cases were confirmed by operation and pathology.Spiral CT scans were performed in seven cases,contrast scanning were performed in three cases.MPR were performed in two cases.Imaging findings in all cases were retrospectively reviewed.Result：Findings of CT scan in seven patients showed scattered and multiple,unequal-sized nodular shadows and airbag cavity,randomly distributed in the centre and peripheral of lung along the airway,the nodules are homogeneous soft tissue density or liquid density;with air cavity are sac,available for thin-walled cystic wall,or a thick wall,give priority to with thin wall,most of the capsule wall were smooth,part of vesicles were connected to the bronchi,seldom complicated with lung inflammation.Conclusion：Juvenile laryngeal papilloma in the spread of bronchia and lung exhibits some imaging features on spiral CT,which can be the clue for the diagnosis and can be helpful to improve the diagnostic accuracy.
