Abstract

Malignant lymphoma is the second-most common malignancy in the head and neck region. Waldeyer's ring is the most common site of extranodal Hodgkin's lymphoma (NHL) in that region, and a small percentage of primary extranodal NHL occurs in the oral cavity. The most common sites of extranodal NHL in the oral region are the palate and maxilla, and nearly half of extranodal NHL cases arise from bone. It is difficult to diagnose extranodal NHL because of the variety of its radiological features. We report a case of primary extranodal NHL of the maxilla in a 68-year-old female patient with atypical imaging findings, along with the results of analysis of dynamic magnetic resonance imaging (MRI).

摘要

恶性淋巴瘤是头颈部第二常见的恶性肿瘤。瓦尔代尔环是该区域结外霍奇金淋巴瘤（NHL）最常见的部位，一小部分原发性结外NHL发生在口腔。口腔区域结外NHL最常见的部位是腭部和上颌骨，近一半的结外NHL病例起源于骨骼。由于其放射学特征多样，结外NHL难以诊断。我们报告一例68岁女性患者的上颌骨原发性结外NHL，伴有非典型影像学表现，以及动态磁共振成像（MRI）分析结果。
