My sister 54, in China, felt her vision weak seriously day by day. She went to see the doctor in April this year and MRI indicated that there was a brain cyst (29mm x 13mm x 12mm) inside pressing the nerve. She did the surgical operation of neurocranium on April 17 and the cyst was removed. The operation was successful, her vision resumed and she is in recovery. Last week (early July), the vision became worse again and another MRI showed the recurrence of the cyst to the same size in less than 3 month. She doesn’t know what to do next and need the advice if there is any treatment that will prevent the cyst regrow. Please help!!! Thank you so much!
