Three cases of intracranial perineural metastasis from adenoid cystic carcinoma of the head and neck are presented. The metastases presented more than 1 year (14 months to 5.5 years) after the primary tumor had been successfully treated without any evidence of local recurrence. Computed tomography of the intracranial metastasis demonstrated well-demarcated, hyperdense, enhancing extraaxial masses indistinguishable from meningioma. An intracranial extraaxial mass lesion with the appearance of a meningioma in a patient with known adenoid cystic carcinoma of the head and neck, regardless of the presence or absence of local recurrence, should be considered as metastasis until proved otherwise.
本文报告了3例头颈部腺样囊性癌的颅内神经周围转移病例。转移发生在原发肿瘤成功治疗后1年以上（14个月至5.5年），且无任何局部复发迹象。颅内转移的计算机断层扫描显示边界清晰、高密度、强化的轴外肿块，与脑膜瘤难以区分。对于已知患有头颈部腺样囊性癌的患者，无论是否存在局部复发，出现具有脑膜瘤表现的颅内轴外肿块病变，在未得到其他证明之前均应考虑为转移。
