CT findings were compared retrospectively between 9 cases with malignant lymphoma of the anterior mediastinum and 8 cases with invasive thymoma. CT findings of malignant lymphoma were as follows: 1) The majority of the tumors were bilateral and extended beyond the anterior mediastinum to the other mediastinum compartments. 2) Their margin was either smooth or lobulated. 3) Their density was either homogeneous or heterogeneous. In the case with heterogeneous density, ring, triangle and/or band-like low density areas, just like interspace of fused lymph nodes, were demonstrated. Calcification or cysts could not be shown. 4) Patent inherent vessels without deviation were occasionally demonstrated running through the tumors. 5) The tumors faced and contacted widely to anterior chest wall and often pressed the lung laterally at the anterior parietomediastinal pleural reflection. 6) Pleural implants were not demonstrated.
回顾性比较了9例前纵隔恶性淋巴瘤患者与8例侵袭性胸腺瘤患者的CT表现。恶性淋巴瘤的CT表现如下：1）大多数肿瘤为双侧性，超出前纵隔延伸至其他纵隔间隙。2）其边缘光滑或呈分叶状。3）其密度均匀或不均匀。密度不均匀的病例中，可见环形、三角形和/或带状低密度区，类似融合淋巴结的间隙。未显示钙化或囊肿。4）偶尔可见无移位的通畅固有血管穿过肿瘤。5）肿瘤与前胸壁广泛相对并接触，在前胸壁纵隔胸膜反折处常向外侧压迫肺。6）未显示胸膜种植。
