vortex/horn of energy from ajna chakra?

I recently encountered a situation where a (fairly devloped) person has a vortex or horn of energy extending from the ajna chakra. Has anyone come across this in any theosophical/occult teachings? It’s not the telescope from ajna for magnification, etc. Haven’t been able to find any kind of reference in Bailey/Leadbeater/Hodson. Main question is, what does this do (if anything) and how should it be managed?
