A 32-year-old man presented with discoloration of the face (so-called port-wine stains) and seizures since childhood. Axial (A) and coronal T1w (B) post-contrast MRI brain demonstrate cortical atrophy and gyriform calcification with serpentine leptomeningeal enhancement over the right cerebral hemisphere (arrows). These findings are consistent with Sturge-Weber syndrome.
