ABSTRACT
A 14-year-old boy with relapsed T cell acute lymphoblastic leukaemia received reinduction chemotherapy that included nelarabine, a purine nucleoside analogue known to cause dose-dependent neurotoxicity. Although he achieved aminimal residual disease negative remission after two cycles of chemotherapy he also developed severe, progressive peripheral and central neurotoxicities. Loss of grey-white differentiation was seen on a T2-weighted magnetic resonance imaging brain scan. This unusual clinical picture and previously unreported radiological findings are thought to be due to nelarabine toxicity. He was bridged with 6-mercaptopurine while transplant was deferred pending sustainable neurological improvement. This case posed clinical and ethical dilemmas while demonstrating previously unreported radiological features.
