vestibular response in my ears but my hearing levels were normal.My ENT could not understand how that could be so he sent me to get a MRI of the brain with contrast.The only abnormality that showed up was an underlying mass in the pituitary gland.I then had a MRI of the pituitary gland and it showed a 0.5 x 0.5 benign cyst and minimal deviation of the pituitary stalk to the left of the midline.
