 BRACHIAL PLEXUS: There is an approximately 5.3 x 1.8 cm left supraclavicular ill-defined mass that extends into and expands the left C6-C7 neural foramen and tracks along the roots and trunks of the left brachial plexus. There is a well-defined remodelling of the adjacent left C7 vertebral body and left posterior elements. There is no resultant spinal canal stenosis. CERVICAL SPINE:The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is slightly heterogenous, a non-specific appearance. The imaged spinal cord displays normal signal and morphology. There is multilevel disc desiccation and a congenitally narrow cervical spinal canal.C2-C3: There is bilateral facet arthropathy as well as a right paracentral disc osteophyte complex without significant spinal canal or neural foramen stenosis.C3-C4: There is bilateral facet arthropathy, left greater than right, as well as mild bilateral uncovertebral joint arthropathy and a small central disc osteophyte complex. There is moderate left neural foramen narrowing and mild spinal canal stenosis.C4-C5: There is moderate left facet arthropathy and bilateral uncovertebral arthropathy as well as a mild disc osteophyte complex. These findings result in mild bilateral neural foramen narrowing and mild spinal canal stenosis.C5-C6: There is loss of disc height, endplate degenerative change, mild bilateral facet arthropathy, and bilateral uncovertebral arthropathy, left greater than right, as well as a posterior disc osteophyte complex. These findings result in moderate left and mild right neural foramen stenosis and mild spinal canal stenosis.C6-C7: There is mild disc height loss and mild posterior disc osteophyte complex. There is also a left paraspinal mass that is further described in the brachial plexus portion of the report. There is no significant spinal canal or right neural foramen stenosis.C7-T1: There is no disc bulge or herniation, and no significant spinal canal or neural foramen stenosis.
1.Left supraclavicular mass extending along the roots and trunks of the left brachial plexus, as well as into the left C6-C7 neural foramen with adjacent bony remodeling but without associated spinal canal stenosis. The differential diagnosis includes neural tumor such as schwannoma or neurofibroma.2.Mild cervical spine degenerative changes superimposed on a congenitally narrow spinal canal resulting in multilevel mild spinal canal stenosis and multilevel neural foramen narrowing as detailed above.
