Brachial Neuritis After Botulinum Toxin Injections for Cervical Dystonia: A Need for a Reappraisal?

Ilaria Cani et al. Mov Disord Clin Pract. .

Abstract

Background: Brachial neuritis has previously been described as a rare occurrence in patients receiving botulinum toxin for cervical or writing/focal arm dystonia.

Methods: We report four cases of patients with a long history of cervical dystonia treated with botulinum toxin injections.

Results: All patients developed pain and muscular weakness around the shoulder, with EMG studies suggesting brachial neuritis.

Conclusions: In the context of these observations, we discuss the question of an association between brachial neuritis and botulinum toxin treatment.

Keywords: Parsonage‐Turner syndrome; botulinum toxin injections; brachial neuritis; neuralgic amyotrophy.
