case_images: Axial MRI images of the brain. Selected axial MRI images of the brain: FLAIR (A), T1-weighted (B), post-contrast T1-weighted (C), and DWI (D). The images reveal an ill-defined lesion (arrow) within the right lateral ventricle, centered on the septum pellucidum, causing obstructive hydrocephalus.. MRI, magnetic resonance imaging; FLAIR, fluid-attenuated inversion recovery; DWI, diffusion-weighted imaging

case_images: No evidence of adjacent parenchymal invasion or extracranial extension was noted (Figure 1).
case_images: CT image of the brain. Axial CT image of the brain demonstrating a slightly hyperdense lesion (arrow) within the right lateral ventricle with associated hydrocephalus.. CT, computed tomography
