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.
