Non-Hodgkin lymphoma (NHL) is the second most frequent malignant tumor in the head and neck, squamous cell carcinoma being the most frequent. NHL often appears in extranodal localisations. In the head and neck, two distinct extranodal sites are recognised: extranodal lymphatic localisations or involvement of the ring of Waldeyer, and extranodal extralymphatic localisations. In this study we reviewed the imaging features of 55 patients who showed extranodal NHL-localisations to investigate whether we could find specific imaging characteristics. There are no pathognomonic signs. However, if more than one extranodal mass is detected, if the mass appears huge without necrosis or ulceration, if the mass is associated with large, non-necrotic nodes, the diagnosis of non-Hodgkin lymphoma can be suggested; however, it is usually not possible to exclude other pathological processes with absolute certainty.
非霍奇金淋巴瘤（NHL）是头颈部第二常见的恶性肿瘤，最常见的是鳞状细胞癌。NHL常出现在结外部位。在头颈部，有两个不同的结外部位：结外淋巴部位或瓦尔代尔环受累，以及结外非淋巴部位。在本研究中，我们回顾了55例表现为结外NHL部位患者的影像学特征，以研究是否能发现特定的影像学特征。没有特征性征象。然而，如果检测到不止一个结外肿块，如果肿块巨大且无坏死或溃疡，如果肿块与大的、无坏死的淋巴结相关，则可提示非霍奇金淋巴瘤的诊断；然而，通常不可能绝对排除其他病理过程。
