Abstract
We report a patient with proximal right upper limb tremor, secondary to direct peripheral nerve lesion caused by prior thoracic surgery. Electromyography demonstrated neurogenic abnormalities and tremor in muscles innervated by the thoracodorsal and long thoracic nerves. Somatosensory evoked potentials, transcranial magnetic stimulation, and MRI of the cervical and thoracic spine were normal. Tremor persisted in REM and non-REM sleep. These findings suggest a peripheral generator.
