Abstract: 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.
