摘要
目的:探讨高分辨力螺旋CT在不典型结节病鉴别诊断中的价值。方法:回顾性分析20例符合诊断标准的非典型胸部结节病的CT影像表现,并与淋巴结结核、淋巴瘤、转移瘤及矽肺等进行对比分析。结果:本组20例不典型胸部结节病中:①胸部发生部位及钙化性状:发生于一侧肺门及纵隔12例(60.0%)、仅发生于纵隔7例(35.0%)、仅发生于肺门1例(5.0%)、钙化2例(10.0%);②纵隔肿大淋巴结分布情况:中纵隔淋巴结肿大14例(73.7%)、前及中纵隔2例(10.5%)、中及后纵隔1例(5.3%)、前纵隔1例(5.3%)、后纵隔1例(5.3%);③CT强化方式:均匀强化13例(65.0%)、不均匀强化3例(15.0%)、环形强化2例(10.0%)、囊变2例(10.0%);④CT强化程度:明显强化12例(60.0%)、中度强化5例(25.0%)、低度强化2例(10.0%)、无强化1例(5.0%)。结论:不典型结节病的肿大淋巴结部位和CT扫描强化方式及强化程度有其自身的特点,大部分发生于一侧肺门伴或不伴纵隔(以中纵隔为主)淋巴结肿大,CT增强呈明显均匀强化,聚集成团,但境界清晰、互不融合,可有斑点状钙化或囊变。
Objective:To evaluate the value of high resolution spiral CT in the differential diagnosis of atypical thoracic sarcoidosis.Methods:CT features of 20 cases accorded with the diagnostic criteria of atypical thoracic sarcoidosis were retrospectively analyzed,and compared with that of tuberculosis lymphadenopathy,lymphoma,metastatic tumors and silicosis.Results:Of the 20 patients with atypical thoracic sarcoidosis,there were hilar and mediastinal lymphadenopathy(12 cases,60.0%)、mediastinal lymphadenopathy only...
