支气管粘液性填塞为一个独立的临床疾患。其特征是在一叶或多叶肺肺段或分段的支气管内有浓稠的X线可见的粘液性栓子。据报导本症最常见于哮喘患者,但也见于慢性支气管炎,囊性纤维变性及过敏性肺笷状菌病。此外约15％的患者原来并无特殊肺部疾病。本病常被误诊为肺肿瘤或未消散的细菌性、霉菌性或结核性肺炎。本病应与哮喘持续状态、慢性支气管炎或囊性纤维变性患者可能发生的弥漫性粘液性栓塞相鉴别。这些粘液性栓子主要累及较小的气道,分布弥漫,X线不能查见。
Bronchial mucosal packing is an independent clinical condition. It is characterized by a thick, visible X-ray mucinous emboli in the lobes or lobes of the lung or in segmental bronchi. It is reported that this disease is most common in patients with asthma, but also in chronic bronchitis, cystic fibrosis and atopic dermatitis. In addition, about 15% of patients had no specific lung disease. The disease is often misdiagnosed as lung cancer or undisplaced bacterial, fungal or tuberculous pneumonia. The disease should be consistent with asthma, chronic bronchitis or cystic fibrosis patients may occur diffuse mucinous embolization phase identification. These mucous thrombi mainly involve small airways, diffuse distribution, X-ray can not see.
