I am 29 years old and four weeks ago I experienced a cloudy spot in my left eye. I was also experiencing localized headaches on the left side of my head. A CT ruled out a large tumor, but my first MRI showed abnormalities. A spinal tap ruled out infection and last week I had another MRI with spectroscopy. This test showed no increased chemical levels and no change in the size of the "spot". The neurosurgeon from the beginning stated that he was baffled by the presentation on my first MRI and had several others look at it and they too were not sure. He has not made any attempt on a diagnosis and wants to do another MRI in 6 weeks, so I am in the process of seeking a second opinion.
Could you please tell me what you think might be a diagnosis based on this MRI explanation: Focal areas of increased T2 signal intensity in the left thalamus, basal ganglia, and left temporal lobe as well as the focal area of increased T2 signal intensity in the right occipial lobe. These findings represent a demyelinating process of unknown etiology. These are stable and unchanged since the prior study of 3/8/06 and do not appear to represent neoplasm on the spectroscopy images. A small cyst is demonstrated near this area and may represent a small choroid fissure cyst.
Any help would be appreciated. Do you recommend any other tests that have not been done?
