title: Surgical removal of the solitary metastasis of renal cell carcinoma in the third ventricle using an interhemispheric transcallosal trans-choroidal approach.
abstract: We herein describe a case of a solitary metastasis of renal cell carcinoma (RCC) in the third ventricle, which was totally removed via an interhemispheric trans-callosal trans-choroidal approach. The histological examination revealed a solitary metastasis of RCC. The postoperative course was uneventful. A stereotactic cyber knife was additionally used for the tumor cavity. As of 2 years after surgery, the patient has been doing well without recurrence. This case highlights the urgent need for an early diagnosis and surgical treatment for solitary metastasis of RCC to the third ventricle due to its critical course.
