目的研究严重急性呼吸综合征(SARS)康复患者肺部残留病灶的CT表现及其转归。方法83例临床治愈患者出院1个月后进行X线胸片和CT检查,对肺部有病灶的病例间隔2个月后再次复查X线胸片和CT,对两次随访检查结果进行对比并分析肺部残留病灶与SARS类型的关系。结果30.1%(25/83)病例肺部存在残留病灶,CT表现包括磨玻璃影6例,网状影5例,片状影3例,索条影2例,磨玻璃影和上述其他病灶混合影9例,2个月后复查除两例外均有不同程度吸收;SARS重型病例肺部残留病灶比例(36.8%)高于普通型(15.4%),两者差异有统计学意义。结论部分临床治愈SARS患者肺部存在残留病灶,CT表现以磨玻璃影、网状影为主,SARS重型病例肺部残留病灶比例高于普通型,这些病灶经治疗大部分有不同程度吸收。
Objective To study the CT findings and prognosis of residual lung lesions in patients with severe acute respiratory syndrome (SARS) rehabilitation. Methods Eighty-three clinically cured patients underwent radiographic X-ray and CT examinations one month after discharge. Two-month X-ray and CT were performed on patients with lesions in the lung. The results of two follow-up examinations were compared and analyzed Analysis of the relationship between residual lung lesions and SARS types. Results There were residual lesions in the lungs in 30.1% (25/83) cases. The CT findings included 6 cases of ground-glass opacities, 5 cases of reticular deformities, 3 cases of lamellar-like lesions and 2 cases of clasping shadow. The ground-glass shadow was mixed with the above- There were 9 cases (9.8%) of patients with severe SARS. The proportion of remaining pulmonary lesions in severe cases (36.8%) was higher than that of common type (15.4%). There was a statistically significant difference between the two cases. Conclusions Some clinically cured SARS patients have residual lesions in the lungs. The CT appearances are ground-glass shadow and reticular shadow. The proportion of residual lung lesions in severe cases of SARS is higher than that of ordinary ones. Most of these lesions are absorbed to varying degrees.
