Objective To investigate the multi-slice CT findings of primary mediastinal tumors and tumor-like lesions. Methods A retrospective analysis of 92 cases of pathologically confirmed primary mediastinum CT data. Results Common lesions were thymoma in 6 cases, thymoma in 31, teratoma in 8, lymphoma in 6, thymus cyst in 3, mediastinal cyst in 9, neurogenic lesions in 12, seminoma in 2, 2 cases of pericardial disease and 2 cases of vascular tumor. There were 3 cases of yolk sac tumor, 2 cases of Castleman’s disease and mediastinal mesothelioma, 1 cases of amyloidosis, mucinous liposarcoma, neuroendocrine carcinoma and myelolipoma, respectively example. Conclusion Multi-slice spiral CT has important value in the diagnosis and preoperative evaluation of mediastinal tumor or tumor-like lesions.
