Malignant lymphomas represent approximately 5% of all malignant neoplasms of the head and neck. The head and neck region is the second most frequent anatomical site of extra-nodal lymphomas (after the gastrointestinal tract). Most are non-Hodgkin's lymphomas of B-cell lineage, and overall diffuse large B-cell lymphoma is the most common type. They can present in highly variable appearances in different anatomical subsites in the head and neck. There is little literature on their imaging appearances on different imaging methods including ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), and integrated positron-emission tomography (PET)/CT. The review aims to illustrate the presentation of histopathological-proven extra-nodal lymphoma in the head and neck using various imaging methods.
恶性淋巴瘤约占头颈部所有恶性肿瘤的 5%。头颈部是结外淋巴瘤的第二常见解剖部位（仅次于胃肠道）。大多数是非霍奇金淋巴瘤的 B 细胞谱系，弥漫性大 B 细胞淋巴瘤是最常见的类型。它们在头颈部的不同解剖部位可能表现出高度可变的外观。关于不同影像学方法（包括超声、磁共振成像（MRI）、计算机断层扫描（CT）和正电子发射断层扫描（PET）/CT ）的影像学表现，文献很少。本综述旨在使用各种影像学方法说明经组织病理学证实的结外淋巴瘤在头颈部的表现。
