Neurologic signs and symptoms in acute lymphocytic leukemia are often secondary to CNS leukemia.1 Cerebrospinal fluid pleocytosis is usually present in such cases.1 Dural sinus occlusion is a rare complication of CNS leukemia and may produce neurologic signs and symptoms without CSF pleocytosis.2 We recently evaluated a patient with acute lymphocytic leukemia in bone marrow remission. Signs and symptoms of CNS leukemia developed in this patient, without CSF pleocytosis. There was occlusion of the superior sagittal sinus and other major venous channels but no evidence of infection or CNS leukemia. This seems to be a unique occurrence.
