Occipital headaches. Chiari malformation. Assess for syrinx or cord tethering. The odontoid process is retroflexed. There is cervical spinal sagittal straightening. Please refer to the previous cervical spine MRI report for other details.Thoracic alignment is anatomic. The vertebral bodies are preserved in height. There is no suspicious focal marrow lesion. There is disc desiccation at T7-T8 and T8-T9 with mild height loss. The other discs are relatively preserved in height. The spinal canal is notable for mild narrowing at T10-T11 caused by facet arthropathy and right greater than left ligamenta flavum thickening which minimally indents the right posterolateral aspect of the thecal sac and abuts the spinal cord. There is also narrowing of the left T10-T11 neural foramen by facet arthropathy and a cyst, which may represent a perineural cyst or less likely a synovial cyst related to the facet. The cyst measures axially 0.7 cm x 0.4 cm. Cervical spinal cord is notable for diffuse mild dilatation of the central canal (from T4 level through lower T12 level but most pronounced at mid T7 level measuring axially 3 mm x 3 mm). The conus medullaris has normal shape and its tip is located at the L1-L2 level.Right ventrolateral to spine at the level of T5-T6 disc, there is a 10 mm x 6 mm well-circumscribed, homogeneously T2-hyperintense, T1-hypointense structure which probably reflects focal dilatation of the thoracic duct. Alternatively but less likely, this may represent a small focal foregut duplication cyst or even lymphatic malformation.
1.Mild thoracic syrinx, measuring up to 3 mm at mid T7 level.2.Mild spinal canal stenosis at T10-T11 cause by facet arthropathy and ligamenta flava thickening. A small left T10-T11 neural foramen cyst may represent either a perineural or less likely synovial cyst.3.Small right ventral paraspinal cyst at T5-T6 level may represent focal dilatation of the thoracic duct, a small focal foregut duplication cyst or lymphatic malformation.4.Normal position of the conus medullaris tip.5.Please refer to the report of the brain MRI from the same day for more details regarding the Chiari malformation.
