背景:Swyer-James-MacLeod综合征(SJMS)是一种罕见的肺部疾病,其特征是单侧肺功能亢进和肺血管系统减少,有或没有支气管扩张。在1950年代,Swyer,詹姆斯,麦克劳德首次同时描述了这种综合征。它通常在儿童时期被诊断出来。成人发病病例极为罕见,关于其临床表现和诊断挑战的文献很少。Swyer-James-MacLeod综合征可以模仿其他肺部疾病,导致误诊和不当治疗。
方法:一位来自DebreBerhan的49岁女性,埃塞俄比亚,向HakimGizaw教学医院急诊科介绍了类似急性肺栓塞的症状和影像学检查结果。根据临床表现和影像学检查结果,该患者首先被视为可能的肺栓塞病例。开始抗凝治疗和氧支持。然而,使用胸部计算机断层扫描血管造影术进行的其他测试显示左肺过度透明,血管减少,支气管扩张,肺栓塞的阴性结果.因此,诊断为Swyer-James-MacLeod综合征。
结论:Swyer-James-MacLeod综合征的症状可能被误认为是肺栓塞,这可能导致无效的治疗和不必要的费用。在出现提示肺栓塞症状的个体中,该病例强调了将Swyer-James-MacLeod综合征作为鉴别诊断的重要性,特别是在没有确定肺栓塞危险因素的情况下。
BACKGROUND: Swyer-James-MacLeod syndrome (SJMS) is a rare lung condition characterized by a unilateral lung hyperlucency and reduction in the pulmonary vasculature, with or without the presence of bronchiectasis. In the 1950s, Swyer, James, and Macleod simultaneously characterized the syndrome for the first time. It is typically diagnosed in childhood. Adult-onset cases are extremely rare, with little literature available on its clinical presentation and diagnostic challenges. Swyer-James-MacLeod syndrome can mimic other lung disorders, resulting in misdiagnosis and improper treatment.
METHODS: A 49- year-old woman from Debre Berhan, Ethiopia, presented to the emergency department of Hakim Gizaw Teaching Hospital with symptoms and radiographic findings mimicking acute pulmonary embolism. On the basis of the clinical presentation and radiographic findings, the patient was first treated as a probable case of pulmonary embolism. Anticoagulant therapy and oxygen support were initiated. Nevertheless, additional testing using a chest computed tomography angiography revealed left lung hyperlucency, decreased vascularity, bronchiectasis, and a negative result for pulmonary embolism. As a result, Swyer-James-MacLeod syndrome was diagnosed.
CONCLUSIONS: The symptoms of Swyer-James-MacLeod syndrome can be mistaken for pulmonary embolism, which could lead to ineffective treatment and needless expenses. In individuals presenting with symptoms suggestive of pulmonary embolism, this case emphasizes the significance of considering Swyer-James-MacLeod syndrome as a differential diagnosis, especially in the absence of established risk factors for pulmonary embolism.
