摘　　要：The current report focuses on two patients of the same age who presented similar appearances on initial anteroposterior chest images. Follow-up images showed superoanterior and superoposterior mediastinal lesions. The first patient with noninvasive cystic thymoma was suspected before surgery, while the pathologic diagnosis was intrathoracic phrenic nerve schwannoma. The second patient was with an asymmetric, dumbbell-shaped paravertebral tumor over T3 and T4 on the left side. The preoperative diagnostic images were interpreted as showing a neurogenic tumor. However, the pathologic report was cell chondrosarcoma.The current report focuses on two patients of the same age who presented similar appearances on initial anteroposterior chest images.
