Malignant lymphomas are differentiated into Hodgkin's and non-Hodgkin's-lymphoma (NHL). The following article discusses the imaging of extranodal NHL in supradiaphragmatic localizations. Lymphoma can affect nearly all tissues, and represent a rare entity as primary extranodal NHL. A secondary involvement of non-nodal tissue as consequence of a generalized lymphoproliferative disease is more common,and may be seen as well in HIV-positive patients defining AIDS. As extranodal lymphoma mimic the radiologic appearance of other malignant tumors, direct diagnosis without histologic analysis is often impossible. The article describes typical manifestations of lymphoma of the lungs, the head and neck area including the large glands, and rare localizations as the heart or the breast.
恶性淋巴瘤可分为霍奇金淋巴瘤和非霍奇金淋巴瘤（NHL）。以下文章讨论膈上部位结外NHL的影像学表现。淋巴瘤几乎可累及所有组织，作为原发性结外NHL是一种罕见的疾病。作为全身性淋巴增殖性疾病的结果，非淋巴结组织的继发性受累更为常见，在定义为艾滋病的HIV阳性患者中也可见到。由于结外淋巴瘤模仿其他恶性肿瘤的放射学表现，通常无法在没有组织学分析的情况下直接诊断。本文描述了肺部、头颈部（包括大腺体）淋巴瘤的典型表现，以及心脏或乳腺等罕见部位的表现。
