OBJECTIVE
To assess the prevalence of high-attenuation mucous plugs observed on chest computed tomography (CT) scans in patients with allergic bronchopulmonary aspergillosis.
PATIENTS AND METHODS
The CT scans of 14 patients with allergic bronchopulmonary aspergillosis, seen between July 1990 and July 1994 at a single tertiary-care institution, were reviewed. The presence and distribution of high-attenuation mucous plugs were recorded in each case.
RESULTS
High-attenuation mucous plugs were present in 4 (28%) of the 14 patients. Mucous plugging was unilobar in three of these four patients. Mucous plugging with attenuation similar to that of chest wall muscle was not found in any of the patients with high-attenuation plugging.
CONCLUSIONS
High-attenuation mucous plugs occur in approximately one quarter of patients with allergic bronchopulmonary aspergillosis and may be more common in patients with unilobar plugging.
目的
评估变应性支气管肺曲霉病患者胸部计算机断层扫描（CT）中观察到的高密度黏液栓的患病率。
患者与方法
回顾了1990年7月至1994年7月在一家三级医疗机构就诊的14例变应性支气管肺曲霉病患者的CT扫描结果。记录每例患者中高密度黏液栓的存在情况及分布。
结果
14例患者中有4例（28%）存在高密度黏液栓。这4例患者中有3例的黏液栓形成局限于一个肺叶。在任何有高密度黏液栓的患者中均未发现其衰减程度与胸壁肌肉相似的黏液栓形成。
结论
高密度黏液栓见于约四分之一的变应性支气管肺曲霉病患者，且在黏液栓局限于一个肺叶的患者中可能更为常见。
