摘要
目的 研究传染性非典型肺炎CT征象特点。方法 对 1 1例传染性非典型肺炎临床确诊患者的CT检查资料进行回顾性分析。结果 8例患者表现为多发边缘模糊的球形和结节状或片状实变 ,密度不均匀。 3例为单发密度不均匀、边界不清的团块状病灶。1例患者可见线状、网状阴影。所有病例均见晕轮征 ,5个邻近胸膜的病灶见方形征。实变病灶中伴有空气支气管征 5例。 3例病变邻近肺野内见磨玻璃阴影。胸膜增厚 3例 ,少量胸腔积液 2例。结论 传染性非典型肺炎的CT征象为非特异性急性感染性病变 ,CT检查有助于本病的早期诊断和鉴别诊断。
Objective To study the CT features of sever acute respiratory syndrome(SARS). Methods We investigated retrospectively CT findings of 11 cases with SARS, the diagnosis were established on clinical findings. Results Multiple poorly defined peripheral spherical and nodular or patchy comsolidations with inhomogeneous attenuation were present in 8 cases. Solitary ill-define inhomogeneous mass was seen in 3 cases. Reticular and linear opacities were shown in 1 case.The halo sign was noticed in all cases and the square sign was seen in 5 lesions that were adjacent to the pleura.We found large consolidations with air bronchograms in 5 cases,ground-glass appearance in 3 cases, small pleural effusion in 2 cases and focal pleural thickening in 3 cases. Conclusion CT features in these cases demonstrate acute nonspectific inflammation, CT examination is very helpful to the early diagnosis and the differential diagnosis of SARS.
