case_images: Figure 2 illustrates the main challenges in the differential diagnosis of lesions in VRS, highlighting both typical and atypical features identified in this case.
case_images: A (axial T2-weighted): Axial image showing hyperintensity characteristic of multiloculated subcortical cystic lesions; B (axial T1-weighted): axial image showing hypointensity, suggesting a lesion with cystic or cerebrospinal fluid content; C (FLAIR): axial image demonstrating hypointensity, indicating iso-intensity to cerebrospinal fluid.

case_images: FIG3
case_images: Signal characteristics showed T2 hyperintensity, FLAIR/T1 hypointensity, and an absence of contrast enhancement or diffusion restriction, findings consistent with the hypothesis of ectatic VRS in a tumefactive presentation (Figure 3).
