fascicular sign
Fascicular sign is a finding on T2-weighted MRI images that suggests a lesion of neurogenic origin. It is characterized by multiple small ring-like structures with peripheral hyperintensity representing the fascicular bundles within the nerves.
It is found in various neurogenic tumors, including:
- neurofibroma
- schwannoma/neurilemoma
- malignant peripheral nerve sheath tumor (PNST): a spindle cell carcinoma arising from a nerve or a neurofibroma
