 There are post treatment findings within the right neck including T2 hyperintensity within the right neck soft tissues, including in the region of the inferior portions of the right brachial plexus, but without discernible abnormal enhancement of the nerve roots. In addition, there is diffuse T2 hyperintensity and diminished bulk of the right trapezius muscle. There also appears to be mild compensatory hypertrophy of the right levator scapula. There are several subcentimeter neural foramen perineural cysts in the cervical spine at multiple levels, but no evidence of significant neural foramen or spinal canal stenosis. There is no evidence of mass lesions along the right brachial plexus or significant lymphadenopathy in the neck. Likewise, there is no evidence of mass lesions in the tongue base. However, there is a left thyroid nodule that measures up to approximately 10 mm. The imaged intracranial structures are grossly unremarkable.
1. Post-treatment findings within the right neck with denervation injury of the right trapezius muscle and possibly mild inferior right brachial neuritis, but no evidence of mass lesions in the region of the right brachial plexus or tongue base.2. Several subcentimeter perineural cysts in the cervical spine at multiple levels, but no evidence of significant neural foramen or spinal canal stenosis. 3. A nonspecific left thyroid nodule measures up to approximately 10 mm. A thyroid ultrasound may be useful for further evaluation.
