A 55-year-old man treated with 5-fluorouracil and oxaliplatin for advanced sigmoid colon cancer presented with seizures, progressive gait and balance difficulties with frequent falls and slurring of speech. After three cycles of chemotherapy, brain magnetic resonance imaging using diffusion-weighted imaging clearly revealed the presence of high signal intensity in the deep white matter of the bilateral cerebral hemispheres, including the corpus callosum symmetrically. A diagnosis of acute leukoencephalopathy was made based on these findings. His clinical symptoms normalized after the discontinuation of the chemotherapy. Early detection of drug-induced leukoencephalopathy is important as the clinical symptoms can be reversed by early discontinuation of the causative drug. Diffusion-weighted magnetic resonance imaging is a useful modality for the early detection and definitive diagnosis of this characteristic encephalopathy.
