case_images: FIG1
case_images: A computed tomography scan of the brain revealed a hyperdense focus in the subependymal location of the occipital horn of the left lateral ventricle (Figure 1).
case_images: Axial MRI brain images including T2-weighted (A), FLAIR (B), and gradient echo (C) revealing a subependymal lesion (arrow) at the occipital horn of the left lateral ventricle. The lesion exhibits high signal intensity on T2 and FLAIR (A and B) with a surrounding rim of low signal intensity. Additionally, the gradient echo image (C) displays a blooming artifact, characteristic of cavernoma.. FLAIR: fluid-attenuated inversion recovery.

case_images: The cavernoma measured approximately 1.2 cm in diameter and was close to the occipital horn of the left lateral ventricle (Figure 2).
