Hello, I am 42yr female with a left sided 5.6 * 4.3 arachnoid brain cyst. Over the past week I have had many symptoms. ie headache, dizziness, changes in vision, have sore neck and have felt faint all week. I went to ER and got an updated CT scan that showed no growth in the size. How successful is the surgery to remove these types of cyst s?
Hi, I had gone through your question and understand your concerns.First arachnoid cysts are not uncommon, and they are benign. Over the years different surgical techniques have been applied to remove or Chat Doctor.  The main reason why are these cysts removed is headache, but there is no evidence that headache is related to the cyst. Furthermore, the headache does not disappear after cyst removal. The recurrence of cyst formation remains high. The only reasonable indication for surgery is cyst dimension growth. So basically if your cyst, which probably is an incidental finding, remains the same, do not worry about, and don't think of surgery, because it will not take your headache away. Just have an MRI every two to three years to check the dimension, and avoid head contact activities or sports, because it has been released with higher incidence of subdural hematomas in pts harboring an arachnoid cyst. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
