弥漫性肺病变系指胸片上广泛分布于两肺的点状、斑片状、结节状、网状及其混合的阴影。可以产生此类病变的疾病有100种以上,多为间质性肺病变。由于诊断手段不多,故误诊情况严重。尽管单纯依靠X线表现作为确诊依据的病例不多,但仔细分析X线特征有助于缩小鉴别范围。结合临床资料,配合必要的实验室检查(特别是病理、微生物检查),多数病人可及时确诊。本文总结我们的经验以冀提高今后的诊断水平。
Diffuse lung disease refers to the chest on the widely distributed in both lungs dot, patchy, nodular, reticular and mixed shade. There are more than 100 diseases that can produce such diseases, mostly interstitial lung disease. Misdiagnosis is serious because of few diagnostic methods. Although only rely on X-ray findings as the basis for the diagnosis of few cases, but careful analysis of X-ray features will help narrow the identification range. Combined with clinical data, with the necessary laboratory tests (especially pathology, microbiological examination), most patients can be diagnosed in time. This article summarizes our experience in order to raise the level of future diagnosis.
