We believe this is the first case report of a pneumothorax being identified using cardiac magnetic resonance imaging. This case also illustrates the haemodynamic effect a large pneumothorax can have on right ventricular filling in diastole.
A 26-year-old attended for an interval follow up Cardiac Magnetic Resonance (CMR) of his thoracic aorta after a thoracic co-arctation repair aged 3. He was found to have an incidental large pneumothorax by the reporting cardiology fellow which was confirmed by the on-call radiologist. The pneumothorax was most notable for its compression of the right ventricle in diastole. Although the patient had worrying features on CMR imaging, he remained clinically stable and a conservative approach to management saw the pneumothorax resolve after a 3 week period.
Pneumothoraces are important, potentially life threatening conditions. Although very rarely identified on MR imaging, radiographers and reporting doctors should be aware of their key features. This case serves to identify not only the abnormal lung parenchymal features but also the striking compressional effect of the pneumothorax on the right ventricle in diastole. Indeed we believe this is the first case report of a pneumothorax identified on CMR imaging.
我们认为这是首例通过心脏磁共振成像确诊气胸的病例报告。该病例还说明了大量气胸对舒张期右心室充盈的血流动力学影响。
一名26岁男性，3岁时接受胸主动脉缩窄修复术后，前来进行胸部主动脉的心脏磁共振成像（CMR）定期随访。报告的心脏病学研究员发现其意外患有大量气胸，值班放射科医生予以确认。该气胸最显著的特点是在舒张期压迫右心室。尽管患者在CMR成像上有令人担忧的特征，但他临床仍保持稳定，采取保守治疗方法后，气胸在3周后得以缓解。
气胸是重要的、可能危及生命的病症。尽管在磁共振成像上很少被发现，但放射技师和报告医生应了解其关键特征。本病例不仅识别出异常的肺实质特征，还发现了气胸在舒张期对右心室的显著压迫作用。事实上，我们认为这是首例通过CMR成像确诊气胸的病例报告。
