摘要
目的:探讨恶性淋巴瘤及纵隔淋巴结转移在SCT增强扫描中的表现,提高其诊断与鉴别诊断的准确性.方法:收集2000年～2004年经穿刺活检病理及临床观察证实的恶性淋巴瘤13例(共55个淋巴结)及纵隔淋巴结转移者28例(共86个淋巴结)的增强SCT所见;观察和评价增大淋巴结的大小、形态、密度、强化特征等方面并对其进行对比分析.结果:淋巴瘤多为均一强化(25/55,45.5%)或呈薄壁环形强化(15/55,41.8%);纵隔转移淋巴结为厚薄不一环形强化和不均匀结节状强化(73/86,84.9%) .结论:SCT增强扫描有助于纵隔淋巴瘤与淋巴结转移的诊断与鉴别诊断.
Objective：To evaluate the conrtast enhanced SCT manifestations of lymphoma and to compare with features of metastatic lymph nodes on mediastintun.Methods： Enhanced SCT findings in 41 patients with pathological or clinical-proved were retrospectively. The lesions included lymphoma 13 cases （including 28 mediastinal lymph nodes）and lymph node metastasis 28 cases（including 86 mediastinal lymph nodes） . The CT findings of the cases were studied retrospectively. Results： Lymphema was hemogeneons enhancement（25/ 55 ,45.5% ） or central soft tissue density with a very thin enhanced capsule （15/55,41.8%）. The lymph node with heterogonons enhancement and with low-density and irregular peripheral enhancement were more common in metastasis （73/86,84,9%）. Conclusion： The enhanced SCT is helpful for the diagnosis and differention diagnosis of lymphema and metastatic lymph node.
