肺部韦格内肉芽肿的CT表现

CT MANIFESTATION OF WEGENER'S GRANULOMATOSIS IN LUNG DISEASE

1目的 探讨肺部韦格内肉芽肿 CT征象的特点与鉴别诊断价值。 2方法 对 7例经病理检查证实的韦格内肉芽肿病人的肺部 CT表现进行回顾性分析。3结果 6例表现为肺内多发性结节 ,2例出现地图状病灶 ,3例可见基底贴附于胸膜面的楔形阴影。多数结节和楔形阴影内可见空洞 ,增强扫描呈边缘性强化 ,2例显示供养血管征。 4结论 肺内多发性结节并部分结节内空洞形成 ,伴有楔形阴影和肺泡浸润性病变对韦格内肉芽肿的诊断具有相对特异性 ,而这些病灶的特殊变化规律更具诊断价值。

Objective To study the character of CT manifestation and the value of differential diagnosis of Wegener's granulomatosis in lung disease.\ Methods\ The lung CT manifestations of 7 patients with Wegener's granulomatosis verified by pathology were retrospectively reviewed and analysed.\ Results\ Multiple pulmonary nodules of soft dense appeared in 6 cases on CT scans, the map like pulmonary infiltritive dense in 2 cases,the peripheral wedge shaped shadows on the pleura in 3 cases. There were cavities in most of nodules and cuneiform structures. Nodules and cuneiform structures demostrated central hypodensity and perpheral enhancement. Vascular sign appeared in 2 cases. \ Conclusion\ Multiple pulmonary nodules, some of which present cavities, accompanied by wedge shaped shadows and map like pulmonary infiltrative shadows are relatively characteristic to diagnosis of Wegener's granulomatosis. The specific variations of the leisions are more valuable than the patterns of them. [
