We report three patients in whom neurologic symptoms and cortical laminar n
ecrosis developed after immunosuppressive treatment (cyclosporin A and FK 5
06) and polychemotherapy (vincristine and methotrexate). Initial neuroradio
logic studies showed cortical and white matter involvement. Follow-up studi
es showed cortical hyperintense lesions on T1-weighted MR images, consisten
t with cortical laminar necrosis, The clinical and radiologic data indicate
that a transient hypoxic-ischemic process could have been responsible for
the encephalic lesions in these three patients.
