A A plexiform neurofibroma involves more than just fatty tissue as being a variant of peripheral nerve tumor. Since it is not just fatty tissue, Kybella or a bile acid that is used to emulsify fat for absorption will not be indicated. Location, surrounding structures, as well as size of the lesion are an important factors when deciding treatment approach / excision. Seeing a Neurosurgeon/ Neuro-oncologist that specializes in this type of lesions would be helpful! Hope this helps!
