My 19 month old child was recently diagnosed with an Arachnoid Cyst after I noticed a boney bump on the right side of his head, just above his temple. I have only heard the Radiologist's report from my pediatrition and I have since made an appointment with a Neurologist. I am concerned because thus far it seems they are opposed to surgery, yet everything I've read has indicated that there is a chance for enlargement or hemorrhaging, which would cause permanent damage. I'm desperate for alternate opinions and/or justification for not operating. Any advice would be greatly appreciated!
