Patients with cavernous hemangiomas of the brainstem can usually survive for decades or even live as long as a normal person if the amount of bleeding is relatively small and is treated in time, but if the amount is large, the patient’s life will be in danger at any time. For patients with cavernous hemangioma of the brainstem with small amount of bleeding, the condition can be controlled through timely treatment, and the survival time is relatively long, which may be as long as several decades, or even the same as the normal life expectancy. However, if the bleeding of brainstem cavernous hemangioma is more, causing a series of complications, such as increased intracranial pressure, intracranial pressure edema and other conditions, or not get timely treatment, then the patient may be life-threatening at any time, and some of the patients can die in a few hours or days. Occurrence of brainstem cavernous hemangioma hemorrhage should be timely medical treatment, and under the guidance of a professional physician, so as not to delay the condition and affect the prognosis.
