Adenoid cystic carcinomas (ACC) make up 3%-5% of head and neck malignancies. They have a high propensity to metastasise, in particular to the lungs. A 65-year-old male diagnosed with a right lacrimal gland ACC T2N0M0 (surgically resected 12 years prior) presented with an incidentally noted 1.2 cm right lower lobe lung nodule seen on MRI liver. Subsequent imaging confirmed a non-FDG avid 1.6 cm solitary ovoid subpleural lesion, percutaneous biopsy confirmed adenocarcinoma. A surgical metastasectomy was performed and recovery was complete. Prognosis in ACC is improved with radical management of metastatic disease. Rather than a simple chest radiograph, more detailed imaging, such as MRI or CT scanning may increase the probability of early detection of pulmonary metastasis and, thereby facilitate radical treatment and improve survival.
腺样囊性癌（ACC）占头颈部恶性肿瘤的3% - 5%。它们具有较高的转移倾向，尤其是转移至肺部。一名65岁男性，12年前被诊断为右泪腺ACC T2N0M0（已手术切除），此次肝脏MRI检查偶然发现右肺下叶有一个1.2 cm的结节。后续影像学检查证实为一个1.6 cm的非FDG摄取的孤立卵圆形胸膜下病变，经皮活检确诊为腺癌。遂行手术切除转移灶，患者完全康复。对转移性疾病进行根治性治疗可改善ACC的预后。相较于简单的胸部X线片，更详细的影像学检查，如MRI或CT扫描，可能会增加早期发现肺转移的概率，从而有助于根治性治疗并提高生存率。
