Leukemia-induced brain hemorrhage is very serious and requires immediate hospitalization. Cerebral hemorrhage caused by leukemia is an indirect effect of leukemia because leukemia causes leukopenia and thrombocytopenia, which leads to bleeding due to clotting dysfunction. Higher amounts of cerebral hemorrhage may lead to increased intracranial pressure, causing symptoms such as headache and projectile vomiting; in severe cases, cerebral herniation may occur, endangering the patient’s life. Cerebral hemorrhage in leukemia patients can lead to serious sequelae, and some patients may have abnormal vital signs at any time. In order to prevent secondary bleeding and further increase in bleeding, it is necessary to go to the hospital in time for platelet transfusion and other treatments to maintain vital signs. In addition, bone marrow transplantation is preferred for complete treatment of leukemia. Patients with leukemia triggering cerebral hemorrhage are advised to actively cooperate with the treatment under the doctor’s advice so as not to miss the best treatment time.
