A 45-year-old female patient presented with symptoms of polydipsia and polyuria, menopause, headache, gait disturbance and deteriorated mental state. Brain magnetic resonance imaging (MRI) showed an irregular mass in the anterior third ventricle. The tumor was excised using a transfrontal approach from the anterior section of the third ventricle. The histological diagnosis was of an intracranial pure yolk sac tumor. The patient underwent radiotherapy and suffered no tumor recurrence one year after the surgery. Overall, when heterogeneous enhancement and an irregular mass with surrounding invasion and ventricular dilation are observed in the anterior third ventricle of an adult, a yolk sac tumor should be considered, and MRI may aid the differential diagnosis. A combination of surgical resection and radiotherapy is recommended for the yolk sac tumor.
一名45岁女性患者出现多饮、多尿、绝经、头痛、步态障碍及精神状态恶化等症状。脑部磁共振成像（MRI）显示第三脑室前部有一不规则肿块。采用经额叶入路从第三脑室前部切除肿瘤。组织学诊断为颅内纯卵黄囊瘤。患者接受了放疗，术后一年无肿瘤复发。总体而言，当在成人第三脑室前部观察到不均匀强化、伴有周围浸润和脑室扩张的不规则肿块时，应考虑卵黄囊瘤，MRI可能有助于鉴别诊断。对于卵黄囊瘤，建议采用手术切除和放疗相结合的治疗方法。
