Not the same: Brain lesions can be anything seen on an MRI or ct ranging from old trauma, old strokes, signs of multiple sclerosis, infections, abnormal vessels (just about anything). We usually don't call tumors 'lesions'...We call them tumors. With technology today, we see lots of stuff on mri's that we aren't actually sure what it is, so we call them 'lesions' and watch them.
