Acute respiratory failure in hyperleukocytotic acute myeloid leukemia: the role of perfusion lung scintigraphy.
A patient with acute hyperleukocytotic myelogenous leukemia who presented with acute respiratory distress is reported. Clinical manifestations included dyspnea, tachypnea, hyperventilation, and cyanosis. ⋯ Pulmonary leukostasis syndrome (PLS) was later confirmed at autopsy. In a patient with hyperleukocytosic from acute nonlymphocytic leukemia and respiratory distress, a normal perfusion lung scintigraph should make one consider the PLS.
