The occipital interhemispheric transtentorial approach is commonly used for pineal region tumors. However, there are few reports of this approach for lesions in the superior cerebellum. We present a 47-year-old male patient with an incidental cystic lesion in the superior cerebellum, detected on MRI consistent with cerebellar hemangioblastoma. The patient initially underwent stereotactic radiosurgery. After 5 months he presented with dizziness. A repeat MRI scan revealed an interval increase in lesion size. We performed surgery using the occipital interhemispheric transtentorial approach to remove the lesion. There were no intraoperative complications and the patient tolerated the procedure well. We describe our approach, supplemented by a short video, and review operative approaches to the superior cerebellum.
枕下入路经天幕间常用于松果体区肿瘤。然而，对于小脑上病变，采用该入路的报道较少。我们报告了一例 47 岁男性患者，其小脑上意外发现囊性病变，MRI 符合小脑血管母细胞瘤。患者最初行立体定向放射外科治疗。5 个月后出现头晕，重复 MRI 扫描显示病变大小间隔增加。我们采用枕下入路经天幕间入路手术切除病变。术中无并发症，患者耐受良好。我们描述了我们的手术方法，并附有简短的视频，同时回顾了小脑上病变的手术入路。
