目的研究先天性马蹄肺的MSCT表现,提高对该病的认识和诊断能力.方法回顾分析5例先天性马蹄肺的影像学及临床资料,全部患者采用CT平扫,其中4例经增强扫描及三维重组技术重组图像.结果 5例呈左或右下肺基底段肺组织向对侧延伸,从脊柱、食管、降主动脉前方,心脏后方以狭长的峡部互相融合,所有患者均伴有支气管及肺的发育不良,支气管异常起源,异常动脉血供,4例伴有部分性肺静脉异位引流至下腔静脉及不同的心血管畸形.结论 MSCT平扫、增强及三维重组技术能清晰显示先天性马蹄肺的病变特征及伴随的气管、支气管、心血管的异常.

Objective To study the multi-slice helical CT (MSCT) features of horseshoe lung and to improve its diagnostic ability. Methods The clinical and imaging data were retrospectively reviewed in 5 patients. All of them underwent plain MSCT scan, and 4 patients also had enhanced MSCT scan and threedimensional reconstruction. Results In horseshoe lung, the basal segments of the right and left lungs were fused together by a isthmus of pulmonary parenchyma, across the midline behind the pericardium and before the esophagus, descending aorta and spine. All patients were companied with bronchopulmonary dysplasia,anomalous origin of the central bronchi, anomalous arterial supply. Anomalous pulmonary venous return to inferior vena cava and congenital cardiovascular malformations were also found in 4 cases. Conclusion MSCT and three-dimensional reconstruction are valuable for identification of horseshoe lung.
