BELLA ROMERA, S et al. Brachial plexus schwannoma and botulinum toxin: a case report. []. , 28, 4, pp.242-245.   08--2021. ISSN 1134-8046.  https://dx.doi.org/10.20986/resed.2021.3924/2021.

Brachial plexus schwannomas are tumors developed from the neural sheaths of rare presentation, but benign evolution. They can cause symptoms, generally of the neuropathic type, due to local growth with the consequent compressive effect of noble neural structures such as the roots of the brachial plexus.

Botulinum toxin is a neurotoxin synthesized by the bacterium Clostridium Botulinum. Its mechanism of action consists of selectively blocking the cholinergic receptors of the neuromuscular junction, producing a temporary and reversible neuromuscular paralysis, recovering function in approximately three to six months.

We present the case of a patient diagnosed with brachial plexus schwannoma with increasing compre­ssive effect who was treated with botulinum toxin in the scalene muscles.
