Abstract：Intracranial primary melanoma is a rare tumor,yet it is extremely rare in the fourth ventricle.The prognosis of patients varies due to differences in tumor differentiation degree,location,and extent of resection.Hence,accurate preoperative diagnosis,complete tumor resection during the operation as much as possible,and supplemented with postoperative radiotherapy are the keys to improving the prognosis of patients.This paper reports a case of an 81-year-old patient.Both preoperative head CT and enhanced MRI examinations indicated a tumor in the fourth ventricle.After completing preoperative preparations,the tumor was completely resected under the microscope.During the operation,it was discovered that the occipital skin,the inner plate of the occipital bone,the meninges,and the cortex were all conspicuously blackened.Postoperative pathology confirmed primary melanoma.Although the patient was of advanced age,the clinical symptoms disappeared after the operation,and he was able to take care of himself in daily life.No tumor recurrence was found in imaging examinations 10 months after the operation,nor was distant metastasis detected.This indicates that for elderly patients with primary ventricular melanoma,by strictly grasping the surgical indications and conducting adequate preoperative preparations,surgical treatment can be considered.
