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

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.
