Question: Can a temporal arachnoid cyst be dangerous ?

Hi Antoine, arachnoid cysts are something that people are usually born with and that many people will never even realise they have. On the whole they are not dangerous but in some rare cases they can grow in size and cause problems. But every patient needs to be considered individually and if there are any concerns the patient should seek medical attention. (This isn’t medical advice!)
