Reason: thoracic syrinx and fatty filum, follow up after hospitalization for pain crisis. please do on 3 T scanner with tethered cord protocol. Thoracic spine: Alignment is anatomic. The vertebral bodies are normal in height. There is no suspicious marrow signal abnormality. There is disc height loss at T7-T8 without significant disc herniation. The spinal canal and the neural foramina are preserved.Again seen is a thoracic syrinx predominate from the upper T5 to the upper T7 level with minimal prominence of the central canal more superiorly as well as inferiorly extending to the conus. There is no significant change in size. Syrinx is maximal at the T5-T6 level where it measures 2 x 3 mm in the AP and transverse dimension which is similar to prior.There are tiny pleural effusions, also present previously.Lumbar spine: Alignment is anatomic. The vertebral bodies are preserved in height. Of note, L5 is partially sacralized. The spinal canal and the neural foramina are preserved. Intervertebral disks are normal. The conus terminates at the inferior L1 level which is within normal limits. Fatty signal within the filum terminale at L2-L3 has not changed and remains very thin and short segment.Prone images demonstrate appropriate ventral motion of the conus.There are free fluid in the pelvis which appears prominent for patient's age.
1. Unchanged small thoracic syrinx compared to 11/20/2015. 2. Conus terminates at the inferior L1 level. Mild fatty infiltration of the filum terminale at L2-L3 again seen. There is appropriate ventral motion of the conus on prone sequences. There is no clear evidence of cord tethering by imaging but can be correlated with clinical findings.3. There is small to moderate amount of free fluid in the pelvis which appears slightly prominent for patient's age. This finding is nonspecific.
