Hi .....I had a car accident last year someone went into the back of my car...since then I have had chronic head aches, tiredness and fatigue...now I have numbness in my arm and face....they gave me a MRI and they found i have an arachnoid cyst at the back of the head...2.8cm x 1.9cm x 1.1cm.....is this big ...they are now referring me to the specialist should I be worried
Hello, The arachnoid cyst is, in most cases, an incidental finding, during imaging examinations done for other reasons. Probably it was there since birth, and in most of the cases, it does not cause any symptoms. Only in rare cases when there is evidence of adjacent brain compression, it needs neurosurgical attention. So, see a Neurosurgeon for this issue. Hope I have answered your query. Let me know if I can assist you further.
