Cerebellar metastasis is a condition in which malignant tumors from other parts of the body metastasize to the parenchyma of the cerebellum. There may be symptoms such as dizziness, headache, vomiting, mostly jet vomiting, unstable walking, etc. The causes of these symptoms are cranial hypertension and local symptoms of the metastases. To treat the above causes, first of all, it is necessary to lower the cranial pressure treatment, mostly applying mannitol, glycerol fructose, hormones, etc. There are also treatments for cerebellar metastases, local radiotherapy, including gamma knife, three-dimensional stereotactic radiotherapy, and drugs that can effectively cross the blood-brain barrier, such as bevacizumab and ocitinib for lung cancer tumors, etc. With the reduction of cranial hypertension and the effective control of metastases, the vomiting symptoms will be gradually relieved.
