Preoperative three-dimensional (3D) imaging of a mediastinal tumor using two-dimensional (2D) axial computed tomography is sometimes difficult, and an unexpected appearance of the tumor may be encountered during surgery. In order to evaluate the preoperative feasibility of a 3D mediastinal model that used the rapid prototyping technique, we created a model and report its results. The 2D image showed some of the relationship between the tumor and the pericardium, but the 3D mediastinal model that was created using the rapid prototyping technique showed the 3D lesion in the outer side of the extrapericardium. The patient underwent a thoracoscopic resection of the tumor, and the pathological examination showed a rare middle mediastinal ectopic thymoma. We believe that the construction of mediastinal models is useful for thoracoscopic surgery and other complicated surgeries of the chest diseases.
使用二维（2D）轴向计算机断层扫描对纵隔肿瘤进行术前三维（3D）成像有时很困难，并且在手术过程中可能会遇到肿瘤的意外外观。为了评估使用快速成型技术的3D纵隔模型的术前可行性，我们创建了一个模型并报告其结果。二维图像显示了肿瘤与心包之间的一些关系，但使用快速成型技术创建的三维纵隔模型显示了心包外侧面的三维病变。患者接受了胸腔镜下肿瘤切除术，病理检查显示为罕见的中纵隔异位胸腺瘤。我们认为纵隔模型的构建对于胸腔镜手术和其他胸部疾病的复杂手术是有用的。
