Can lymphangioma be a rare side effect from lip filler? If so, what can be done to fix it?

I have a linear ridged growth under my top lip after getting lip filler back in April 2022. I have since gotten the filler dissolved, but the linear ridge is still there. I read an article stating that lymphangioma can be a rare side effect of lip filler. Is this true and if so what can be done to fix it, also could it get worse? Thanks!
