Summary
Researchers found 23 intracranial lipomas using MR imaging, including three solitary choroid plexus lipomas. These findings suggest choroid plexus lipomas may be more common than previously believed.
Area of Science:
- Neuroradiology
- Neuroimaging
- Pathology
Background:
- Intracranial lipomas are rare benign tumors.
- Choroid plexus lipomas are a subtype, often found incidentally.
- Previous literature suggests they are uncommon.
Purpose of the Study:
- To report the incidence of intracranial lipomas.
- To characterize solitary choroid plexus lipomas.
- To reassess the prevalence of choroid plexus lipomas.
Main Methods:
- Retrospective review of MR imaging studies.
- Identification and classification of intracranial lipomas.
- Comparison of detection rates between MR imaging and CT.
Main Results:
- Twenty-three intracranial lipomas were identified.
- Three cases of solitary choroid plexus lipomas were found, all located at the trigone.
- One small choroid plexus lipoma was detected by MR imaging but not by CT.
Conclusions:
- Solitary choroid plexus lipomas are not as rare as previously thought.
- MR imaging is a sensitive tool for detecting these lesions.
- Further investigation into their prevalence is warranted.
