We report the case of a 35-year-old woman in whom a systematic thoracic x-ray led to the diagnosis of unilateral hyperlucent lung due to a carcinoid tumor obstructing the main left bronchus almost completely. Injected computed tomography permitted diagnosis of left lung hypoperfusion and visualization of the tumor. After enlarged inferior left lobar resection, normal perfusion was observed six months later on the isotopic lung perfusion scan. Other reported causes of unilateral hyperlucent lung are discussed as well as pathophysiological mechanisms of lung hypoperfusion and hypoxic vasoconstriction.
我们报告了一例35岁女性病例，其通过系统性胸部X光检查诊断为单侧肺透亮度增加，原因是类癌肿瘤几乎完全阻塞了左主支气管。注射式计算机断层扫描有助于诊断左肺灌注不足并显示肿瘤。在进行左下叶扩大切除术后，同位素肺灌注扫描显示六个月后灌注恢复正常。文中还讨论了其他已报道的单侧肺透亮度增加的病因，以及肺灌注不足和低氧性血管收缩的病理生理机制。
