A 40-year-old woman developed acute onset of right-sided weakness with ipsilateral partial motor seizures. She had a 6-month history of well-controlled rheumatoid arthritis treated with certolizumab (a biological pegylated tumour necrosis factor (TNF)-α inhibitors). MR scan of brain showed diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) hyperintensity of the left fronto-parietal cortex without apparent diffusion coefficient (ADC) signal restriction and left-sided …
