Patient Data

Age: 16 years
Gender: Female

There is a cortical-based "bubbly" appearing mass in the right parietal lobe. The coronal FLAIR image shows characteristic ring-like hyperintense signal (bright rim sign). No perifocal edema and no contrast-enhancement are present. Incidental note is made of a septation within the left ventricle.

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
