Abstract

A 73-year-old man was admitted to Toyama Red Cross Hospital, because of productive cough and right flank pain. His chest X-ray film and computed tomography (CT) showed pleural effusion and a mass shadow in the right lung area. On CT vessels and bronchi were seen curving toward the mass (comet tail sign), suggesting rounded atelectasis. Transthoracic lung biopsy under CT and echo guidance revealed suppurative pleuritis. MRI also showed the comet tail sign. Moreover, in the lesion, curling hypointense lines were observed on various slices. We describe how MRI facilitates the diagnosis of rounded atelectasis.

摘要

一名73岁男性因咳痰和右侧胁腹疼痛入住富山红十字医院。他的胸部X光片和计算机断层扫描（CT）显示有胸腔积液以及右肺区域有一个肿块阴影。在CT上可见血管和支气管向肿块弯曲（彗尾征），提示圆形肺不张。在CT和超声引导下进行的经胸肺活检显示为化脓性胸膜炎。磁共振成像（MRI）也显示了彗尾征。此外，在病变部位的各个层面上观察到卷曲的低信号线条。我们描述了MRI如何有助于圆形肺不张的诊断。
