Abstract

High-resolution computed tomographic scans of 19 patients with pulmonary asbestosis revealed a subpleural curvilinear shadow (SCLS) parallel to the inner chest wall in the lungs of 15 (78.9%) patients. Most (46.7%) SCLS measured greater than 5 cm but less than 10 cm in length and occurred less than 1 cm from the inner chest wall in all cases. SCLS was distributed mainly in the lower lobe in patients with mild pulmonary fibrosis and in segments where fibrosis was mild in patients with honeycomb shadows. This may reflect initiation of pulmonary fibrosis leading to the formation of a honeycomb shadow. Radiologic-pathologic correlation, achieved in one postmortem specimen, seemed to indicate that SCLS was associated with the initial change of fibrosing bronchioloalveolitis, which is characteristic of pulmonary asbestosis.

摘要

对19例肺石棉沉着病患者进行的高分辨率计算机断层扫描显示，15例（78.9%）患者肺部出现与胸壁内侧平行的胸膜下曲线形阴影（SCLS）。大多数（46.7%）SCLS长度大于5 cm但小于10 cm，且在所有病例中均出现在距胸壁内侧不到1 cm处。SCLS主要分布在轻度肺纤维化患者的下叶以及有蜂窝状阴影患者纤维化较轻的节段。这可能反映了导致蜂窝状阴影形成的肺纤维化的起始阶段。在一份尸检标本中实现的放射学-病理学相关性似乎表明，SCLS与肺石棉沉着病特征性的纤维性细支气管肺泡炎的初始变化有关。
