case_images: CT and MRI scan showing hyperintense perilesional edema. A and D are selective images of an unenhanced CT scan of the brain at the level of the centrum semiovale and posterior horn of the right lateral ventricle, respectively. They exhibit an iso- to hyper-dense, well-defined lesion with surrounding vasogenic edema (arrow) within the right parietal lobe.. B and E are T2-weighted images at the same mentioned levels, displaying a hypointense lesion superiorly and hyperintense content inferiorly with a hypointense rim (arrowhead on E) and surrounding hyperintense vasogenic edema (arrow).. C and F show the same lesion on T1-weighted images without contrast, demonstrating a gradient of hyperintense content with a hypointense rim and hyperintense perilesional edema (arrow).

case_images: FIG1
case_images: A CT and MRI of the brain were obtained, which showed a gradient of hyperintense content of the lesion with surrounding relatively hyperintense perilesional edema (Figure 1). T1-weighted images displayed a gradient of hyperintense content of the lesion with surrounding relatively hyperintense perilesional edema. The most inferior aspect of the lesion exhibited hyperintense content with a rim of hypointensity, featuring a popcorn appearance (Figure 1).
case_images: MRI T1 images post contrast. A and D are T1-weighted images post-contrast with subtraction images (B and E) at two different levels of the same lesion showing a thin rim of enhancement. On susceptibility-weighted images (C and F), the lesion contained a susceptibly effect and a relatively higher rim of susceptibility.

case_images: The post-contrast images showed a margin of thin enhancement, best seen in subtraction images (Figure 2).
case_images: CT and MRI scans. The lesion showed a fluid-fluid level, which is best displayed by the coronal T2-weighted image (A) and sagittal T1-weighted image (B). Status post excision of the lesion with immediate post-operative changes are noted on an unenhanced CT scan of the brain (C and D).

case_images: FIG3
case_images: T1 weighted sequences (Figure 3A-3B), displayed the extent of the lesion and the fluid-fluid level. The constellation of the findings were most consistent with a cavernoma. The post-operative CT scan showed the expected immediate post-operative changes without complications or residual lesion (Figure 3C-3D).
