The reason for the MRI, I think, is the phrase " A superimposed right lumbosacral motor radiculopathy cannot be fully excluded." This indicates there is some evidence that some of your symptoms may be due to compression of nerve roots on the right side of your lumbar/sacral spine. (A radiculopathy is a compression of nerve roots adjacent to the spine--"radic" is Latin for "root".)

It's not unusual for some people to have neuropathy from some systemic cause, such as diabetes, made worse by additional nerve compression. This is, in fact, referred to as a "double crush syndrome" in which an already compromised nerve tract is further damaged by mechanical compression and the symptoms may actually be greater than the presumed sum of the parts (once a nerve is damaged it doesn't take much compression to really cause it problems).
