Acute myeloid leukemia (AML) is a hematologic malignancy that can present with central nervous system (CNS) symptoms. Neurological symptoms may result from the local accumulation of malignant cells in or near the brain (chloroma), infection, hemorrhage, or infarcts from leukostasis. Leukostasisis a syndrome that can include brain infarction due hyperviscosity of blood with vascular occlusion but CNS involvement is rarely encountered in adults. We report an unusual case of leukostasis in an adult who presented with multiple high attenuation intracranial masses on CT. While initially thought to represent chloromasthey proved to be hemorrhagic infarcts secondary toleukostasis on open brain biopsy. This condition is under-reported in the radiology literature and only rarely biopsy proven. We review in this paper the pathological, CT and MRI findings of leukostasis in order to increase awareness of this uncommon entity and facilitate diagnosis.

Extreme hyperleukocytosis (Leukocyte count >200 × 10/L) in an adolescent young adult (AYA) patient with B-ALL could result in mild symptoms of leukostasis. Hyperleukocytosis requires prompt initiation of therapy with adequate hydration, cytoreduction and prevention of tumor lysis. Ph + B-ALL may present with extreme hyperleukocytosis and may be resistant to initial pre-phase therapy.

Introduction: Patients with acute myeloid leukemia (AML) are at high risk of developing life-threatening complications. It is estimated that a quarter of adult patients diagnosed with AML will require admission to the intensive care unit (ICU) at least once during their disease. Acute respiratory failure (ARF) is the main reason for ICU admission and is associated with high mortality rates, depending on the etiology of ARF.

Purpose: We report the second case of bilateral sudden sensorineural hearing loss with intracochlear fibrosis due to chronic myeloid leukemia.
Case Report: A 44-year-old man presented to the emergency department with rapidly progressive bilateral hearing loss, tinnitus and vertigo, associated with dyspnea. Chronic myeloid leukemia complicated by pulmonary and cochleovestibular leukostasis was diagnosed, and cytoreductive treatment was started.

Purpose: AML presenting with hyperleukocytosis is associated with poor outcomes. We aim to understand the factors associated with early mortality and overall survival (OS) to help guide management and improve early mortality.
Methods: We retrospectively reviewed data from 129 consecutive patients with newly diagnosed AML and a WBC count ≥100 × 10/L between January 2010 and April 2020.
