Delayed leukoencephalopathy with stroke-like presentation in chemotherapy recipients.
A transient leukoencephalopathy mimicking cerebrovascular accident has been described as a complication of chemotherapy, most commonly in recipients of intrathecal methotrexate for childhood leukaemia. Recently published neuroimaging data suggest a common pathophysiology associated with a variety of chemotherapy agents and modes of administration. ⋯ Several pathophysiological models of delayed leukoencephalopathy after exposure to intrathecal or systemic chemotherapy have been proposed. DWI findings in this cohort are indicative of cytotoxic oedema within cerebral white matter and lend support to an at least partially reversible metabolic derangement as the basis for this syndrome.
