The parotid gland and its lymph nodes are frequent sites of metastases from head and neck cancers. However, metastasis from a distant primary below the clavicle is unusual. These originate from a variety of sites, most commonly the lung, kidney and breast. A case of a 59-year-old woman with parotid lymph node metastasis from an adenocarcinoma of the urachus, diagnosed on the basis of two discrete periparotid masses on CT and the patient's history, is presented.
腮腺及其淋巴结是头颈部癌症转移的常见部位。然而，锁骨以下远处原发灶转移至腮腺则较为罕见。这些转移灶起源于多种部位，最常见的是肺、肾和乳腺。本文报告一例59岁女性，其腮腺淋巴结转移性腺癌起源于脐尿管，根据CT上两个孤立的腮腺周围肿块及患者病史得以诊断。
