Breast cancer and C3-C4 autofusion (Klippel-Feil?): right upper extremity pain and tingling sensation, with decreased strength throughout. There are multiple Multiple unchanged congenital anomalies of the cervical spine, including incomplete fusion of the posterior elements of C1, a C4 butterfly-type vertebra fused with the C3 vertebral body, and dysplasia of the C5 posterior elements. There is no significant spondylolisthesis. There is also multilevel degenerative spondylosis. At C2/3, ligamentum flavum thickening and facet arthropathy result in mild to moderate left foraminal narrowing with mild bilateral neural foraminal narrowing, but no significant spinal canal stenosis. At C3/4, there is mild to moderate narrowing of the bilateral neural foramina, but no significant spinal canal stenosis. At C4/5, there is bilateral mild to moderate foraminal narrowing. At C5/6, a disc-osteophyte complex results in severe narrowing of the right neural foramen and moderate narrowing of the left neural foramen, as well as mild right paracentral narrowing of the spinal canal. At C6/7, a disc-osteophyte complex, ligamentum flavum thickening, and facet arthropathy result in moderate narrowing of the spinal canal, as well as severe bilateral neural foraminal narrowing. Aside from degenerative signal alterations, the vertebral bone marrow signal appears unremarkable. The spinal cord appears unremarkable. There is no evidence of mass lesions in the cervical spine. The paraspinal soft tissues are unremarkable.
1. Multiple congenital segmentation anomalies in the cervical spine and degenerative spondylosis that is most pronounced at the C5/6 and C6/7 levels.2. No evidence of metastases in the cervical spine.
