Pneumothorax after needle electromyography is a rare complication, which usually associated with examination of diaphragmatic and intercostal muscles. However, by the literatures, it can also occur with supraspinatus, serratus anterior and paraspinal muscles. We experienced a case of pneumothorax after cervical paraspinal muscle needle electromyography. From the anatomical vulnerability of pneumothorax during needle insertion, we emphasized the importance of avoiding this complication.
