This pictorial essay aims to present various lesions that could present as consolidations with diffuse of focal high attenuation on computed tomography, helping to make the diagnosis more confident and specific. The radiologic literature has limited information about such findings and the role of computed tomography in the differential diagnosis. The following diseases are presented: metastatic pulmonary calcification, pulmonary alveolar microlithiasis, amiodarone lung, talcosis, iodinated oil embolism, tuberculosis, silicoproteinosis, and amyloidosis. In conclusion, air-space consolidations can be seen in a wide variety of diseases affecting the lungs. The identification of the different patterns of consolidation with focal high attenuation narrows the differential diagnosis. We present a diagnostic approach based on appearance and distribution of these lesions.
这篇图文并茂的文章旨在展示各种在计算机断层扫描上可表现为实变并伴有弥漫性或局灶性高密度影的病变，有助于更准确、更具特异性地做出诊断。放射学文献中关于此类发现以及计算机断层扫描在鉴别诊断中的作用的信息有限。本文介绍了以下疾病：转移性肺钙化、肺泡微石症、胺碘酮肺、滑石肺、碘化油栓塞、肺结核、硅蛋白沉着症和淀粉样变性。总之，肺部多种疾病均可出现气腔实变。识别不同的伴有局灶性高密度影的实变模式可缩小鉴别诊断范围。我们基于这些病变的表现和分布提出了一种诊断方法。
