Wallerian degeneration (WD) is the anterograde degeneration of axons following a proximal neuronal injury [
1]. In the brain, WD has been described as commonly affecting the corticospinal tract after various insults [
2,
3]. Diffusion-weighted imaging (DWI) and diffusion tensor imaging sequences on magnetic resonance imaging (MRI) can precisely detect WD from the altered water content of affected tracts days to months after the initial insult [
4‐
6]. Its behavior on apparent diffusion coefficient (ADC) is variable [
7]. We describe the unique case of WD of corticobulbar fibers in the brain visualized as a restrictive lesion on MRI-DWI sequences 13 months after an intracerebral hemorrhage (ICH). …
