(3)肺部炎性病变 (一)结核病:肺内纤维包围性干酪性病变,结核性空洞堵塞,其内容物失水浓缩而成球形病变,包围式的原发性肺结核病灶,或肺结核病灶初发现时就呈球形,多发生于锁骨之下,即Assmann氏病灶等在肺野内造成圆形边缘明显的阴影。这种阴影常在健康检查时发现,或在观察已发现的肺结核病患者的病变过程中发现。阴影的大小,一般自0.5—3厘米,多数位于肺上部。阴影可能是浓度均匀的,也可能有钙化点,也可以发生液化形成空洞(图1)。
(3) pulmonary inflammatory disease (a) tuberculosis: pulmonary fibrosis surrounded by cheese disease, tuberculous voids, the contents of water-concentrated from spherical lesions, surrounded by primary pulmonary tuberculosis, or pulmonary tuberculosis Initially found spherical, mostly in the collarbone, Assmann’s lesions in the lungs caused by the circular edge of the obvious shadow. This shadow is often found at the time of the health examination or during the observation of the lesion found in patients with pulmonary tuberculosis. The size of the shadow, usually from 0.5-3 cm, most located in the upper lung. Shadows may be uniform in concentration, may also have calcification points, and may also form liquefied voids (Figure 1).
