鼻咽癌(NPC)腮腺转移少见,作者回顾性分析了1916例NPC患者的影像学表现,其中27例(1.4％)在CT(27例)、MR(4例)显示腮腺转移。27例均病理证实为鼻咽癌,其中6例活检证实腮腺转移。27例中男14例,女13例,平均年龄55岁(35～71岁)。11例(41％)为腮腺淋巴结转移,显示边界清楚或不清的增大的腮腺淋巴结;10例(31％)颈上深部淋巴结增大并转移侵及腮腺,腮腺内条状高密度代表受浸润的淋巴管;3例(11％)直接侵犯腮腺;3例(11％)腮腺广泛受累,但无颈部淋巴结转移和NPC直接侵犯表现。
Nasopharyngeal carcinoma (NPC) is rare in the parotid gland. The authors retrospectively analyzed the imaging findings of 1916 NPC patients, of which 27 (1.4%) had CT (27) and MR (4) showed parotid metastasis. 27 cases were pathologically confirmed nasopharyngeal carcinoma, of which 6 biopsy confirmed parotid gland metastasis. There were 14 males and 13 females in 27 cases, with an average age of 55 years (35-71 years). Eleven patients (41%) had parotid lymph node metastases and showed an enlarged parotid lymph node with clear or unclear border. Ten (31%) cervical lymph nodes were enlarged and metastasized to the parotid gland, 3 cases (11%) directly invaded the parotid gland; 3 cases (11%) had extensive parotid involvement but no lymph node metastases in the neck and direct invasion of NPC.
