What Does My MRI Scan Report Indicate?

CAROL
Creatine kinase, genetic testing and evoked potentials.
Detailed Answer:
Hello and thanks for using HCM.
I have read your question and understand your concerns.
Polymyositis affects more the muscles closest to the trunk (hips, thighs, shoulders, upper arms and neck), not only arms.
Since there is a previous cervical condition, syndromes that involve cervical spinal cord and result in arms and hands weakness without, or partial impairment of sensory abilities ( central cord syndrome, anterior cord syndrome ), should be considered.
Since EMG findings resulted in favor of motor neuron involvement, if upper motor neurons are involved or not should be investigated with a brain MRI.
Lower motor neuron could be affected by motor neuron diseases such spinal muscular atrophy (type IV ).
Besides MRI and nerve conduction study with EMG, creating kinase levels in blood, genetic testing and evoked potentials are necessary as investigations in order to achieve a correct diagnosis.
Discuss with your Doctor about these issues.
Hope you found the answer helpful.
Let me know if I can assist you further.
Kind regards.


An infection is very unlikely.
Detailed Answer:
Welcome back and thanks for being on follow up.
An infection results in fewer and it should be noticeable at least on blood work, so it is very unlikely.
Medications may cause peripheral neuropathy as a possible adverse effect, but clinical characteristics and nerve conduction studies are typical for this condition.
Before to consider rare syndromes, diagnostic tests mentioned in our previous conversation, should be carried out.
Hope this helps.
Let me know the tests results.
Greetings.
