ABSTRACT
Intracranial metastasis from renal cell carcinoma is rare. In this study, four patients (age range 56-72 years) were treated for intracranial metastases from renal cell carcinoma. The metastasis was solitary in all four patients and was located in the temporoparietal region in two patients, cerebellum in one patient, and bilateral lateral ventricles in one patient. Preoperative magnetic resonance imaging showed hemorrhage and necrosis in the tumor in all four patients, and one patient had edema in the region of the tumor. All patients were treated with craniotomy for tumor resection, and histopathologic examination showed clear cell carcinoma. Marked bleeding occurred in all patients during the operation, but preoperative direct injection of ethanol into epidural metastases (2 patients) was effective in decreasing intraoperative blood loss. Prognosis was poor with limited survival time (range 2 weeks-45 months), but prognosis was best in the two patients who were treated with postoperative radiation therapy and chemotherapy (survival times 26 and 45 months). To our knowledge, this is the largest report of four uncommon intracranial metastases from RCC in Chinese patients. In summary, intracranial metastasis from renal cell carcinoma should be considered in the differential diagnosis of intracranial tumor because of the high risk of bleeding and poor prognosis.
