In AML, leukapheresis and hydroxyurea are used to cytoreduction; while in ALL, leukapheresis and dexamethasone are used In the present case leukostasis cerebral, all five patients presented with hyperleukocytic leukemia.

The reason is that myeloblasts are larger in size than lymphoblasts and lymphocytes. The sites leukostasis cerebral leukostasis were the lungs in case 1 and the CNS in cases 2 and 3, which were both invalid. Hence, physicians should begin aggressive treatment for leukostasis when the first respiratory or neurological symptoms or sign appear in a leukemic patient with hyperleukocytosis.

This suggested that the poor prognosis of hyperleukocytosis may be leukostasis cerebral to the monocytic differentiation subtypes in AML, while in ALL there is an association with t 9: This is consistent with previous reports in the literature 312 In conclusion, hyperleukocytosis has a significant prognostic implication.


Leukostasis syndrome frequently arises in hyperleukocytosis, with common leukostasis cerebral including the lung and CNS. Leukostasis syndrome is an emergency case with a high rate of early mortality, therefore, the management must be aggressive. The overall aim is to reduce early mortality, however, the pathophysiology of leukostasis remains unclear and future studies are required.

Lippencott Williams and Wilkins; Philadelphia: Acute leukemia with a very high leukocyte count: Biopsies acquired are examined for damage to microvasculature, which serves as evidence of hypoxia through the identification of leukocyte blockage within the tissue.

Due to a leukostasis cerebral 's invasive nature and the risks associated with the procedure, it is only used leukostasis cerebral deemed necessary.


Measurements for arterial pO2 have shown to be falsely decreased in patients with hyperleuckocytosis because of white blood cells ability to utilize oxygen. Pulse oximetry should be used to more accurately assess pO2 levels of a patient suspected to be suffering from leukocytosis.

Automated blood cell leukostasis cerebral may leukostasis cerebral inaccurate due to fragments of blast cells being labeled on blood smears as platelets. The most accurate form of confirming platelet counts is by using a manual leukostasis cerebral count and review of a peripheral smear.

Serum potassium levels may also be artificially elevated caused by a release from leukemic blasts during in vitro clotting process, therefore serum potassium levels should be monitored by herparinized the addition of heparin prevents coagulation plasma samples in order to obtain accurate results of potassium levels.

Disseminated intravascular coagulation may occur in a significant number of patients with presentation of various degrees of thrombin generation, followed by decreased fibrinogen and increased fibrinolysis. These were initially thought to represent chloromas on the basis of head CT appearance, but subsequently proved to be hemorrhagic infarcts secondary to leukostasis on open brain biopsy.
