The pineal region is an unusual site for brain metastasis and most metastatic pineal lesions are asymptomatic. A 53 year-old man presented with severe headache, limitation of upward gaze and diplopia. The patient's neurological examination was unremarkable. Magnetic resonance imaging (MRI) scans of the brain demonstrated a 1.5 x 2 cm well demarcated solitary mass in the pineal region with hydrocephalus. Surgery was performed and adenocarcinoma was diagnosed. A systemic investigation revealed adenocarcinoma of the lung as primary lesion. Although rare, metastatic tumor should be considered in the differential diagnosis of pineal region tumors.
松果体区是脑转移瘤的一个不常见部位，大多数转移性松果体病变是无症状的。一名53岁男性出现严重头痛、向上凝视受限和复视。该患者的神经系统检查无明显异常。脑部磁共振成像（MRI）扫描显示松果体区有一个1.5×2厘米边界清晰的孤立肿块，并伴有脑积水。进行了手术，诊断为腺癌。全身检查发现原发性病变为肺癌。尽管罕见，但在松果体区肿瘤的鉴别诊断中应考虑转移性肿瘤。
