description Two patients with acute myelomonocytic leukemia in central nervous system relapse developed clinical signs and computerized tomographic evidence of leukoencephalopathy five to seven days after intravenous high dose Ara-C therapy. The first patient had received 30 gm of intravenous Ara-C with cranial irradiation (1680 rad in 2 fractions) and intrathecal Ara-C (100 mg X twice) for an intracerebral chloroma and leptomeningeal leukemia. In this patient the leukoencephatlopathy was probably a result of a synergistic effect of the concomitant triple therapy. The second patient had received intrathecal administration of Ara-C and methotrexate for five and one-half months prior to intravenous Ara-C therapy. He developed altered mental status after 24 gm of intravenous Ara-C infusion. CT scan showed changes in the white matter compatible with leukoencephalopathy. In this patient the intravenous Ara-C probably was the precipitating factor of the development of leukoencephalopathy. The possible mechanism of the Ara-C induced leukoencephalopathy is discussed.
