The findings are fairly nonspecific, but since you have been having some symptoms the neurosurgeon will probably want to explore ways of further determining what the findings represent. Some of them, such as the bright areas, may be fluid, and the possible reasons for that are myriad. Since the radiologist wasn't able to decipher them they may be of no consequence or there may be some fluid accumulation due to some process or injury which the neurosurgeon might be better equipped to identify. The pineal cyst is probably not a major concern as they rarely are, and yours is very small. It could be related to the other findings but collectively they don't tell much. Again, the neurosurgeon may have some ideas as to how to connect these to your symptoms (especially the bright area around the left temporal lobe, which may be related to the numbness in the left extremities, which is the only real neurological symptom you have that isn't readily explainable by other means.
Hopefully the neurosurgeon will be able to shed light on what's going on and what the inconclusive findings on the MRI represent. This is difficult to break down at a distance and really does require the expertise of a specialist. Please follow up with us once you've had the consult and we can perhaps help enlarge upon what you learn then.
Good luck to you. Please follow up with us here as needed and update us after your consult.
