Evaluate mass of right brachial plexus and shoulder: discomfort and small mass on right side just below the clavicle and far lateral. There are innumerable tumors involving multiple bilateral cervical and upper thoracic nerve roots, as well more peripheral nerves, including what may correspond to the lesion of clinical concern located inferior to the right clavicle, which measures up to 27 mm. Of note, a mass along the right C6 nerve root is heterogeneous and has increased in size, measuring 28 mm in width, previously 19 mm. While some of the tumors enlarge the neural foramina, there is no evidence of spinal cord compression. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable.
Innumerable peripheral nerve sheath tumors involving multiple bilateral cervical and upper thoracic nerve roots, as well more peripheral nerves, including what may correspond to the lesion of clinical concern located inferior to the right clavicle, which measures up to 27 mm. Of note, a mass along the right C6 nerve root is heterogeneous and has increased in size, which may indicate malignant transformation.
