ABSTRACT
Objective To characterize the CT features of primary mediastinal seninoma. Methods CT scans of 10 cases with pathologically proved primary mediastinal seminoma were retrospectively reviewed.Results 9 of the 10 cases with the maximal dimension of 6. 5 ~ 18.2 cm( mean = 12. 3 cm) were located in the anterior mediastinum and 1 tumor was located in the middle mediastinum. All of the 10 tumors were solid masses and none of cavity, loculus, fat, calcification or fluid was detected. Areas of low density in the center of tumors were seen in 9 cases. Tumors encircling macrovascular or pericardium were seen in 7 cases. Chest wall invasion was detected in 2 cases. Enlarged lymph nodes in supraclavicular or mediastinum were identified in 4 cases. Lung diseases were found in 5 cases. Bilateral pulmonary metastasis was seen in 1 case. Pleural effusions were detected in 4 cases. Pericardial effusions were evident in 5 cases. Conclusion Most of the primary mediastinal seminomas are solid and large mass without calcification or fat. The tumors are usually located in the anterior mediastinum and areas of low density are usually seen in the center of tumors. Some tumors involve in adjacent structures. Seminoma has some features on CT.
