The aim of this study was to evaluate the pulmonary CT findings in patients with Churg-Strauss syndrome to determine the frequency and nature of parenchymal abnormalities.
CT examinations performed at the time of diagnosis in 17 patients with Churg-Strauss syndrome were retrospectively evaluated by two observers who reached a decision by consensus about the presence and nature of parenchymal abnormalities. High-resolution CT (1- to 3-mm collimation) was performed in 14 patients and conventional CT (6- to 10-mm collimation) was performed in three cases.
Predominant CT findings consisted of parenchymal opacification (consolidation or ground-glass attenuation) (n = 10), pulmonary nodules (n = 2), bronchial wall thickening or dilatation (n = 2), interlobular septal thickening (n = 1), and normal anatomy (n = 2). Parenchymal opacification was predominantly peripheral (n = 6) or random in distribution (n = 4).
The most common CT finding in patients with Churg-Strauss syndrome consists of areas of parenchymal opacification that may be random or peripheral in distribution. These findings are nonspecific.
本研究旨在评估变应性肉芽肿性血管炎患者的肺部CT表现，以确定实质异常的频率和性质。
对17例变应性肉芽肿性血管炎患者诊断时进行的CT检查进行回顾性评估，由两名观察者通过共识确定实质异常的存在和性质。14例患者进行了高分辨率CT（准直1至3毫米）检查，3例进行了常规CT（准直6至10毫米）检查。
主要的CT表现包括实质密度增高（实变或磨玻璃样衰减）（n = 10）、肺结节（n = 2）、支气管壁增厚或扩张（n = 2）、小叶间隔增厚（n = 1）以及解剖结构正常（n = 2）。实质密度增高主要位于外周（n = 6）或呈随机分布（n = 4）。
变应性肉芽肿性血管炎患者最常见的CT表现为实质密度增高区域，可呈随机或外周分布。这些表现是非特异性的。
