Do you need nerve biopsy for ms?

Do you need nerve biopsy for ms?

Almost never: However, problem comes when ms plus another peripheral nerve problem coexist. Biopsy for ms would usually involve brain procedure in order to clarify a difficult presentation, such as tumefactive type of lesion, but this is unique. In short, almost never even get testing of peripheral nerves in ms pts. ...Read more

Esr st 50. Severe peripheral neuropathy. Severe nerve pain. Nerve biopsy on my foot next wk.

By the history, her symptoms haven't progressed in a length-dependent manner (especially given the facial sensory involvement) and this points me toward a sensory neuronopathy aka sensory ganglionopathy. These patients would be expected to have proprioceptive impairment-- if she is still a dance instructor, I doubt her proprioception is impaired. If her neuro exam and nerve conduction study are truly normal, I suspect any additional testing will be normal as well. ...Read more
