Torticollis [M43.6], Severely decreased ROM at neck in all directions. Evaluate for spondyloarthropathy or DDD. The examination is significantly degraded by patient motion. There is a nonspecific heterogeneous bone marrow signal intensity. The vertebral body heights are grossly maintained. There is multilevel loss of intervertebral disc space, particularly at C6-7. The spinal cord demonstrates normal signal intensity, within the limitations of motion artifact. There is paucity of the left vertebral artery flow-void diffusely. The paraspinal soft tissues are grossly within normal limits.C2-3: There is no significant disc herniation, neural foraminal stenosis, or spinal stenosis.C3-4: There is a disc bulge causing mild effacement of the ventral thecal sac and perhaps mild bilateral neural foraminal stenosis.C4-5: There is a posterior disc osteophyte complex and hypertrophy of the ligamentum flavum resulting in mild spinal stenosis and left neural foraminal stenosis.C5-6: There is mild left neural foraminal stenosis secondary to posterior disc osteophyte complex and hypertrophy of the ligamentum flavum.C6-7: There is a posterior disc osteophyte complex and hypertrophy of the ligamentum flavum resulting in moderate spinal and moderate right neural foraminal stenosis.C7-T1: There is a small posterior disc osteophyte complex without significant spinal or neural foraminal stenosis.
1. Nonspecific diffusely heterogeneous appearance of the vertebral bone marrow.2. Multilevel degenerative spondylosis of the cervical spine, which is most pronounced at C6-7 due to at least moderate spinal stenosis associated with disc-osteophyte formation.3. The left vertebral artery does not demonstrate normal flow-voids, perhaps due to steno-occlusive disease. MRA or CTA may be useful for further evaluation.
