Is it Plexopathy, radiculopathy or multiple mononeuropathy?
A 25 years old woman presented paresthesias in her right hand ascending to the shoulder, 20 days after her marriage (minding that she wore a traditional wedding dress that is considered heavy), few minutes later she presented sudden muscle weakness on the right upper limb, and then a gradual recovery 4 days after, without a real pain!
The NCS: All neurophysiological parameters are normal, including the lateral antebrachial cutaneous and the medial antebrachial cutaneous
In EMG: ongoing denervation (spontaneous activity +++) just in 3 muscles Deltoid, extensor communis digitorum and supinator with moderately reduced recruitment
No denervation in these muscles: biceps brachii, 1st interosseous and infraspinatus
No imaging at the moment (in progress)
note that she is thin (39kg for 1m57!) There was a bruise on the back of her shoulder! Now is it a slight trauma that she didn't pay attention to or something else, we don't know.
Note also that the incident occurred 20 days ago and it is in the recovery phase.
What do you think dear colleagues?
Do you think it is plexopathy even if all SNAPs are within normal limits or cervical radiculopathy? or maybe a Rucksack Paralysis? looking at the rapid recovery!
Thank you so much

I enjoy participating in the AANEM Connect Forum for a number of reasons. There are very fundamental questions posed on a frequent basis that cause me to pause and ask myself, ‘Why didn’t I think of that?’ Also, I continue to learn new things when others contribute their thoughts and experiences. Connect is an excellent opportunity for members to interact and to address any topic, including those that may not be discussed at an annual meeting or journal article.
