Idiopathic pulmonary ossification is an uncommon and asymptomatic disorder of unknown etiology in which trabeculated bone is found in the lung. It is usually mistaken for more serious entities radiographically, most commonly appearing as branching linear shadows of calcific density involving a limited area of the lung and exhibiting very slow progression; however, the shadows may be round or irregular and bulky. Sometimes the trabeculae are recognizable, and occasionally the lungs demonstrate widespread involvement. The authors describe 8 proven cases, including one in which a bone scan revealed uptake by heterotopic bone in the lung.
特发性肺骨化是一种病因不明的罕见且无症状的疾病，其特征是在肺内发现骨小梁。在影像学上，它通常被误诊为更严重的疾病，最常见的表现是钙化密度的分支状线性阴影，累及肺的有限区域，进展非常缓慢；然而，阴影也可能是圆形、不规则形或较大的。有时骨小梁可被识别，偶尔肺部会出现广泛受累。作者描述了8例确诊病例，其中1例骨扫描显示肺部异位骨有摄取。
