[|Human|] my mother 85 has suddenly had imbalance issues and feels like her eyes are crossed . she has had the cat scan, blood work and now an mri . Doctor said all is clear! no sinus , no inner ear , noe eyes, not tia no tumors..but he noticed a change in the size of her pituitary glad from the mri of 5 years ago. Now he want a contrast mri and blood work to check the pitutary. He said an endocrinologist would be the next route and would probably give her some pill to take down what may be sudden swelling causing her walking like a drunk and seeing double, What do you think?
[|AI|]  Hi, Thank you for posting your query. Based on the symptoms, I would think of a posterior circulation stroke as the first diagnosis. In this condition, there may be lack of blood flow in brain stem and/or cerebellum. Regarding the normal MRI, it happens in some cases. However, a repeat MRI later would show the infarct (blood clot). Regarding pituitary swelling, it is likely to be a small adenoid (benign tumor), which can be confirmed with contrast scan. In any case, her symptoms are not related to the pituitary swelling. Best wishes, Chat Doctor.
