A. your question troubled me... from what i know of bone development - what you say can very much happen but i never heard of a case like that.and i looked a bit about maybe some information about it, but i'm pretty sure that the name you gave is not the disease that she has, it's just a description.

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness
