| 目的 探讨传染性非典型肺炎的CT表现特点,以期提高临床诊断水平。方法 回顾性分析临床诊断的46例传染性非典型肺炎的临床和CT资料。结果 17例表现为单肺叶单个病灶,以两肺下叶(10/17)及右肺上叶(5/17)多见,29例表现为多肺叶多个病灶,以两肺中下叶(14/29)多见,其次部位是:两肺广泛分布(5/29),右肺上叶为主(4/29),左肺上叶为主(2/29),右肺下叶为主(2/29),左肺下叶为主(2/29)。病灶分布于胸膜下(31/46)或胸膜下并中央区(15/46),胸膜面范围较大。形态分为二种:球形(13/46),片状或类似扇形(21/46),多球形并片状或类似扇形12例。密度分为二种:磨玻璃样高密度(36/46)和实变样高密度(10/46)。1~2周复查,病变范围扩大,密度减低,病灶增多(6/7),病变缩小,密度减低(1/7)。1月左右复查,病变完全吸收消失(9/16),病变范围扩大,密度减低,病灶增多(4/16),病变范围扩大,密度减低(1/16),局部遗留少许纤维条索影(2/16)。结论 以下CT征象应为传染性非典型肺炎较可靠的诊断依据:①病灶多发,胸膜下分布或合并中央区病灶;②球形,片状或扇形形态;③磨玻璃样密度;④病灶的CT动态变化。 |

| Objective To study the CT features of SARS and to evaluate its diagnostic value.Methods The authors retrospectively reviewed the clinical manifestations and CT findings of 46 cases of SARS.Results Single lesion in single lung lobe was found in 17 cases.It was often seen in bilateral lower lobes (10/17) and right upper lobes (5/17). Multi-lesions in multi-lung lobes were found in 29 cases.They were often seen in bilateral middle and lower lobes (14/29), with diffusely distribution in bilateral lung (5/29), mainly in right upper lobes (4/29),in left upper lobes (2/29),in right lower lobes (2/29),in left lower lobes (2/29).The lesions in subpleural were discovered in 31 of 46 cases, associated with lesions in middle zone of lung in 15 of 46 cases. Shapes of the lesions were divided into spherical (13/46),fan and patchy shape (21/46).Multi-spherical shapes with patchy were found in 12 cases. Density of the lesions were divided into two types:ground-glass opacity (36/46) and consolidation (10/46). 1-2 weeks later, enlarge, increase, lower density of the lesions were founded in 6 of 7 cases, shrink,lower density in 1 of 7 cases. About one month ,the lesions disppeared in 9 of 16 cases, enlarge, lower density, increase in 4 of 16 cases,enlarge, lower density in 1 of 16 cases, slight focal fibrosis in 2 of 16 cases.Conclusion The following CT features were reliable in determining SARS:①Multi-lesions,subpleural distribution;②spherical, patchy as well as fan shapes;③Ground-glass opacity;④CT dynamic manifestations. |
