Fig. 1

Progression of cerebral white matter abnormalities in a 38-year-old patient affected with adrenoleukodystrophy. Axial fluid-attenuated inversion recovery (FLAIR) images show a slight increase in lesions from September 2020 (a) to July 2021 (b) and an abrupt progression in September 2022 (c). A three-dimensional T1-weighted gradient-echo sequence failed to demonstrate enhancement in July 2021 (e) and September 2022 (f), while on September 2020, magnetic resonance imaging was performed without contrast injection (d, axial T1-weighted image). High b-value on diffusion-weighted imaging constantly shows a fringe of potential disease activity at the edge of lesions (insets in d, e, and f)
