为分析严重急性呼吸综合征(severeacuterespiratorysyndrome,SARS)胸部并发症在X线平片和CT上的表现,提高对SARS影像学表现的认识,回顾分析182例SARS患者950例次X线胸部平片和74例次胸部CT检查结果,重点观察肺内空洞性病变、肺间质纤维化、气胸、纵隔气肿、皮下气肿和胸膜病变。结果根据X线平片和CT所见,在182例患者中,6例患者(3.3%)出现空洞病变,临床诊断为真菌感染;10例(5.5%)出现胸水,8例(4.4%)出现纵隔气肿和皮下气肿,3例(1.6%)出现气胸。另外,在接受胸部CT检查的54例患者中,有17例(31.5%)患者出现不同程度的肺间质改变,6例患者(11.1%)出现胸膜增厚粘连。提示全面了解SARS患者胸部并发症的影像学征象有助于SARS的鉴别诊断和指导临床治疗。
In order to analyze the manifestations of thoracic complication in X-ray and CT on severe acute respiratory syndrome (SARS) and to improve the understanding of SARS imaging features, retrospective analysis of 950 cases of X-ray chest radiographs in 182 SARS patients and 74 cases of chest CT examination results, focusing on the observation of intrapulmonary cavitary lesions, interstitial fibrosis, pneumothorax, mediastinal emphysema, subcutaneous emphysema and pleural disease. Results According to the X-ray and CT findings, 6 of the 182 patients (3.3%) had cavitary lesions and were clinically diagnosed as fungal infections. Pleural effusion occurred in 10 patients (5.5%) and pleural effusion in 8 patients (4.4%) Mediastinal emphysema and subcutaneous emphysema, pneumothorax occurred in 3 cases (1.6%). In addition, of the 54 patients undergoing chest CT examination, 17 (31.5%) had varying degrees of interstitial lung mass and 6 (11.1%) had thickened pleural adhesions. It is suggested that a comprehensive understanding of the imaging features of chest complications in patients with SARS contributes to the differential diagnosis and guidance of clinical treatment of SARS.
