Cervicothoracic spine shows normal cervicomedullary junction. No tonsillar herniation or cord compression. Normal posterior fossa.
Normal lying conus at L1-2 with central canal dilatation from dorsal cord extending to tip of conus. No cord tethering.
Coronal T2 demonstrates dilated central canal of cervicothoracic spinal cord seen mainly in the mid to lower half of thoracic spine. Absent left posterior arch of L3 with an apparent fusion of L2-3 vertebral spinous processes. Central canal dilatation of spinal cord with compression and thinning of dorsal and ventral ganglia. There is no diastematomyelia or paramedian syrinx. Thin element of T1 and T2 linear hyperintense signal is seen in the posterior thecal sac in the lumbosacral segment - consistent with an intrathecal lipomatous component.
Thinner heavy T2 weighted images (axial 3D FIESTA) showing central canal dilatation of spinal cord with compression and thinning of dorsal and ventral ganglia. There is no diastematomyelia or paramedian syrinx.
