[|Human|] I had an MRI done a couple of weeks ago and the report says I have a pituitary tumor and specs of hyperintensity scant chronic ischemic gliosis.  I followed up with an endocrinologist who is doing blood work to check hy hormore levels.  Should I make an appointment to see a neurologist?  Could this gliosis be causing my headaches?
[|AI|]  Hi. Thanks for using Chat Doctor. Chronic ischemic gloss can occur due to small vessels in brain being blocked resulting ischemia where small areas of brain are devoid of blood supply and become dead. These changes are usually common in patients with hypertension and also in older individuals. These changes itself are not a cause of headache. But a pituitary tumor can definitely cause headache and vision problems if it compresses on the optic chiasm.  In any case I advise you to consult a neurologist for further evaluation.
