Plexopathy
Incidence <60 Gy non-zero but low
The brachial plexus begins at the ventral rami of nerve roots at the fifth cervical vertebrae and continues inferiorly to include the nerve roots exiting the neural foramen of the first thoracic vertebrae (Fig. 3). It then passes inferolaterally between the anterior and middle scalene muscles to innervate the cutaneous skin of the upper extremity and numerous muscles including the latissimus dorsi, pectoralis major and minor, levator scapulae, deltoid, and biceps brachii.
