<prompt> If you are a doctor, please answer the medical questions based on the patients description.I was recently diagnosed with a pituitary tumor, after going to a neurologist his assistant informed me that it is not a pituitary tumor but it next to it by my brain...The reason I even found out about this is through an MRI I had because of vision issues that I am having double vision the thing is this is the third incident it seems to come and go with the first time being in 2009, the second in 2011, both with pregnancies, and now this time while I was on an appetite suppressant. What do you think  <response>: Hi, I had gone through your question and understand your concerns. If you had double vision, the tumor infiltrated cavernous sinus, and treatment depends on the kind of tumor. In that area three are the most probable lesions: Pituitary tumor, Meningioma and Chraniopharyngioma. If the size of tumor is small below 3 cm it could be treated by Radiosurgery, if it is greater than 3 cm it needs surgery.Dont delay treatment because there is a serious risk of blindness. Consult a Neurosurgeon. 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.
