UNASSIGNED: 28 adult patients diagnosed with obstructive pneumonia caused by pepper aspiration from January 2016 to September 2022 were enrolled. The CT characteristics of bronchial changes and pulmonary lesions caused by pepper were analyzed and summarized.
UNASSIGNED: Among 28 patients, the most common symptom was cough (26, 92.9%), followed by expectoration (23, 82.1%). Bronchoscopy revealed that peppers were mainly found in the bronchus of the right lower lobe (n = 18, 64.3%), followed by the bronchus of the left lower lobe (n = 5, 17.9%). In combination with bronchoscopy results, the pepper in the bronchus manifested as circular or V/U-shaped high-density, localized soft tissue, and flocculent opacification in 8 (28.6%), 16 (57.1%), and 3 (10.7%) cases on CT images, respectively. The bronchial wall around the pepper was thickened with localized occlusion (n = 19, 67.9%) and stenosis (n = 9, 32.1%). Regarding adjacent bronchi without peppers, extensive wall thickening with stenosis and/or occlusion was found in 23 (82.1%) cases. Distal pulmonary lesions frequently involved two or three segments (21, 75.0%) and mainly presented as patchy consolidation or atelectasis (24, 85.7%).
UNASSIGNED: In combination to a history of eating peppers and clinical symptoms, bronchopneumonia caused by pepper should be highly suspected if U/V-shaped and annular high-density or localized soft tissue density is detected in the bronchi of the lower lobes, accompanied by extensive bronchial wall thickening, stenosis, or occlusion, and consolidation or atelectasis in multiple distal lung segments.
■纳入2016年1月至2022年9月28例因辣椒误吸而被诊断为阻塞性肺炎的成年患者。分析总结了辣椒引起的支气管改变和肺部病变的CT特征。
■在28名患者中,最常见的症状是咳嗽(26,92.9%),其次是咳痰(23,82.1%)。支气管镜检查显示辣椒主要见于右下叶支气管(n=18,64.3%),其次是左下叶支气管(n=5,17.9%)。结合支气管镜检查结果,支气管中的胡椒表现为圆形或V/U形高密度,局部软组织,和絮凝混浊的8(28.6%),16(57.1%),CT图像3例(10.7%),分别。胡椒周围的支气管壁增厚,局部闭塞(n=19,67.9%)和狭窄(n=9,32.1%)。关于没有辣椒的相邻支气管,23例(82.1%)发现广泛的壁增厚伴狭窄和/或闭塞。肺远端病变常累及2个或3个节段(21,75.0%),主要表现为斑片状实变或肺不张(24,85.7%)。
■结合食用辣椒史和临床症状,如果在下叶支气管中检测到U/V形和环形高密度或局部软组织密度,则应高度怀疑由胡椒引起的支气管肺炎,伴有广泛的支气管壁增厚,狭窄,或遮挡,和多个远端肺段的巩固或肺不张。
