History of myxofibrosarcoma grade 2 status post radical resection free flap and postoperative chemo RT: palpable soft tissue prominence in the right sternocleidomastoid muscle. There are post-treatment findings related to composite resection of the right mandible, right neck dissection. There is diffuse right sternocleidomastoid muscle volume loss and fatty atrophy of the residual right hemitongue. There is a 5 mm diameter focus of susceptibility effect in the subcutaneous tissues overlying the mid right sternocleidomastoid muscle. There is also a subcentimeter relatively T2 hyperintense right level 5 lymph node posterior to the mid right sternocleidomastoid muscle. Otherwise, there is no significant cervical lymphadenopathy by size criteria. The remaining salivary glands appear unchanged and the thyroid gland is unremarkable. The cervical spine is unremarkable. The imaged portions of the intracranial structures and orbits are unremarkable.
Post-treatment findings with atrophy of the right sternocleidomastoid muscle. A 5 mm diameter focus of susceptibility effect in the subcutaneous tissues overlying the mid right sternocleidomastoid muscle is nonspecific and may be attributable to treatment effects versus less likely neoplasm. Likewise, a subcentimeter right level 5 lymph node posterior to the mid right sternocleidomastoid muscle is nonspecific.
