Paraganglioma, ameloblastoma and olfactory neuroblastoma are uncommon primary head and neck tumours. When nodal metastases from these tumours occur, they may present later than and with different imaging characteristics compared with squamous cell carcinoma (SCC), demonstrating appearances similar to the primary tumour type rather than features typical of metastatic nodal SCC. We present three cases in which imaging characteristics of nodal metastases in paraganglioma, ameloblastoma and olfactory neuroblastoma mimicked the primary tumour and discuss their implications for clinicoradiological follow-up.
副神经节瘤、成釉细胞瘤和嗅神经母细胞瘤是罕见的头颈部原发性肿瘤。当这些肿瘤发生淋巴结转移时，与鳞状细胞癌（SCC）相比，它们可能出现得更晚且具有不同的影像学特征，表现类似于原发性肿瘤类型，而非转移性淋巴结SCC的典型特征。我们报告三例副神经节瘤、成釉细胞瘤和嗅神经母细胞瘤淋巴结转移的影像学特征酷似原发性肿瘤的病例，并讨论其对临床放射学随访的意义。
