Patient discussion about rostral

Q. I need help with a delicate topic. My neice was diagnoised with Cranial Transannular Where he forehead was once as normal, now it has a forming point in the center to make it look as though her skull is shrinking inward. Please anyone help with any information you may have

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. Cranial means skull, Trans means cross over and Annular means ring. but if you'll find the right name, or if it is really the real name, here is a bit of places you might find information-

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

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.
