The purpose of our study was to show a distinctive appearance of exogenous lipoid pneumonia on thin-section CT that has not, to our knowledge, been previously documented.
On thin-section CT, exogenous lipoid pneumonia is revealed as patchy well-defined areas of ground-glass attenuation with superimposed septal thickening (crazy-paving pattern). Exogenous lipoid pneumonia should be included in the differential diagnosis when thin-section CT reveals a crazy-paving pattern.
我们研究的目的是展示在薄层CT上外源性类脂性肺炎的一种独特表现，据我们所知，此前尚未有相关文献记载。
在薄层CT上，外源性类脂性肺炎表现为边界清晰的斑片状磨玻璃样密度影，并伴有小叶间隔增厚（铺路石样表现）。当薄层CT显示铺路石样表现时，外源性类脂性肺炎应列入鉴别诊断。
