We have read with interest the paper by Nguyen and col- leagues, “Magnetic resonance imaging of dynamic scapular winging secondary to a lesion of the long thoracic nerve” . Magnetic Res- onance (MR) found denervation signs of serratus anterior muscle (SAM), suggesting a long thoracic nerve (LTN) lesion. The authors concluded that MR may represent a completion of clinical and neu- rophysiological examination in cases of LTN injury. We totally agree with the authors about the importance of imaging to evaluate neu- ropathies. On the basis of our experience, also nerve ultrasound (US) should be considered to assess neuropathies, even in small nerves . This technique has widely shown its usefulness to study dif- ferent peripheral nerve diseases: entrapments, traumatic lesions, tumors, immune-mediated and hereditary neuropathies . US shows its role if associated with clinical and neurophysiological examinations and provides crucial data for prognosis, rehabilitation and treatment . Recently, Lieba-Samal and colleagues published US assessment of LTN and they encouraged the use of US for this evaluation .
