Syrinx, follow-up thoracic disk disease Again seen is a thoracic syrinx extending from the T3-T4 to the T7-T8 levels. It again measures up to 5 x 5 mm in greatest axial dimensions at T4-T5. There is diffuse atrophy of the cord with cystic-appearing diffuse myelomalacia at T7-T8. The positioning of the thoracic cord within the thoracic spinal canal is unchanged, with focal ventral kinking centered at the mid T6 level. Exaggerated thoracic kyphosis is again noted.Multilevel spondylotic changes are again noted, without significant interval change. Vertebral body heights are preserved. There is multilevel disc narrowing and desiccation, more conspicuous along the upper to midthoracic spine. Disc narrowing is also noted at L1-L2, with minimal stable grade 1 retrolisthesis at this level as well as of L2 on L3. Small perineural cysts are again seen in the lower thoracic spine.Counting sequences demonstrate additional spondylotic changes along the cervical spine with trace degenerative subluxations of C4 on C5 and C5 on C6.
1. Stable extent and caliber of thoracic syringohydromyelia extending from T3-T4 to T7-T8. Mid thoracic cord atrophy with areas of myelomalacia.2. Stable kinked contour of the mid thoracic cord at the mid T6 level where it abuts the ventral dural surface. Findings again may be related to granulation tissue however transdural cord herniation cannot be excluded. 3. Stable scattered degenerative changes with exaggerated kyphosis. Additional lumbar and cervical spondylotic changes partially visualized.
