There is new enhancement anterolaterally which may represent reactive dural enhancement" on mri notes when i have a meningioma. lay terms, please?

Contrast enhancement: The findings indicate that the contrast you were injected with leaked out, and may represent a reaction of the dura (lining of the brain) to the meningioma. Your meningioma will be monitored with serial MRIs. See your neurologist for further evaluation and discussion. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2797462/

Thick dura: The dura is the tough membrane around your brain. It can get thicker, like your skull can, when there's a meningioma nearby.
