I would go for another opinion. Drainage of such cysts is generally not effective if you research - so part if not all of the outer layer of the cyst needs to be removed so that the cyst does not refill.
Please look for another opinion - and travel if necessary. Send the records ands CDs around and see what other universities or hospitals say.
Thank you so much for answering! Do you know of any Universities or Hospitals will just take CDS and not make us go in to see them? My hospital is too ill to travel. Thanks so much!
I do not know in particular. This site is affiliated with many hospitals so perhaps ask on the expert forum, or search medical publications for papers on CDS and contact the doctors who wrote those papers.
There are mercy or angel flights that may be able to get him where he needs to go.
Wow--I thought I had a large sub-arachnoid cyst (min is 5x5x9 cm!) I think you are already a member of the Arachnoid Cyst Awareness Network--if not you should join this group and maybe one of the other members can give you an answer to your questions.
