Cerebellar hemorrhage may clear up after the edema is removed. Cerebellar hemorrhage hemorrhage occurs in the deep dentate nucleus region of the cerebellar hemisphere, limited to one side, or gradually expanding to the opposite side. The mild form has a slow onset, severe pain in the occipital region with vertigo, vomiting, ataxia, dysarthria, coarse horizontal nystagmus, and other symptoms, and does not result in impaired consciousness. When the hematoma of cerebellar hemorrhage increases in size and presses or breaks into the fourth ventricle, it can cause acute hydrocephalus, resulting in increased cranial pressure and impaired consciousness, and in severe cases, occipital foramen magnum hernia occurs, which requires timely surgical decompression treatment. If the surgical treatment is timely, the consciousness will be gradually recovered after the hematoma is eliminated; if the surgical treatment is not timely, the patient may suddenly fall into coma, breathe irregularly or even stop, and eventually die due to respiratory and circulatory failure. Patients with cerebellar hemorrhage are recommended to receive timely treatment under the guidance of a professional physician to avoid poor prognosis.
