I have recently been asked to do a CT Scan for my T. Mainly because of new and usual symptoms. The continuance of a reverb noise or echo an extra sound after word I hear in my right ear. I believe my doctor suspects Acoustic Neuroma as he ordered an MRI which I refused because I'm claustrophobic. He then suggested a CT Scan which I agreed to. Of course the amount of radiation is acceptable over being confined in a tube for me, I'm an avid sunbather anyhow On the other hand I feel I'm just trying to buy myself some time from the inevitable which is an MRI scan. I would like to know if anyone else on this board had a great number of Acoustic Neuroma Symptoms to find out they had or did not have it. My inner self tells me it is possible as I have had some slight dizziness, some ear pain, feeling of fullness in the ear, some sinus like headaches, and of course the unilateral T. Would love to hear others stories as to diagnoses of T or AN.
