Choroid plexus lipomas are rare lesions that are thought to result from maldifferentiation of the meninx primitiva. While lipomas are usually associated with brain malformations (e.g., midline deformities), isolated choroid plexus lipomas can be seen and may not be as rare as previously thought. They are most commonly found at the trigone, as in the case shown above. Imaging findings are as expected: fat attenuation on CT and signal intensity that follows fat on MRI.
