 CERVICAL SPINE: Redemonstrated is a small caliber syrinx of the cervical cord without significant interval change in size or extent since prior study. The largest transaxial dimension of the syrinx measuring approximately 1.5 mm at the C6 level is unchanged. There is mild straightening of the cervical spine. The vertebral body and disc heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. There is no significant disc bulge, herniation, spinal canal or foraminal stenosis within the cervical spine. THORACIC SPINE: Redemonstrated is a mildly expansile syrinx of the mid to lower thoracic cord extending from T6 to L1 similar to the prior exam. The syrinx at T8 measures 3.9 x 3.9 mm (AP x TR), previously 3.5 x 3.8 mm. The syrinx at T11 measures 3.9 x 3.5 mm (AP x TR), previously 3.9 x 3.5 mm. The cord terminates at upper L2 level. The thoracic spine is in normal alignment, with a normal thoracic kyphosis. The vertebral body and disc heights are well maintained. No worrisome focal marrow signal abnormality is appreciated. There is no significant disc bulge, herniation, spinal canal or foraminal stenosis within the thoracic spine.
1. Stable appearance of syrinx in the cervical and mid to lower thoracic cord, without significant interval change in size and extent from prior exam.2. No significant spinal canal or neural foraminal stenosis.
