How dangerous is a 1.5cm pineal cyst, no hydrocephalus but i have headaches, nausea, tingling and anxiety.

Worthy of removal: It is not life-threatening, but the symptoms can worsen and affect important vision functions. Pain can increase and since the surgery is considered the safest of all brain surgeries w/ nearly zero mortality, it's a good idea. Recovery may take awhile but is almost guaranteed. Talk about all of this w/ neurologist - I'll connect you to one here - Dr. Dariush Saghafi . Best!
