A syrinx is a fluid-filled cavity within the spinal cord (syringomyelia) or brain stem (syringobulbia). At imaging, NMOSD lesions in the spinal cord are usually longer in craniocaudal extent than those in MS (>1.5 vertebral body) and involve the central gray matter of the cord, sometimes seen as longitudinally extensive spinal cord lesions (25) (Figs 4, 7). These applications require some of the smallest, most flexible, and highly-screened cables on the market. The clinical course and severity of the disease can vary greatly, with several clinical variants identified (8).

These bright spotty lesionsfocal internal areas of T2 hyperintensity that are at least as bright as CSF with corresponding low SI at T1-weighted imaginghave recently been shown to be highly specific to NMOSD and are seen in about one-half of patients (25,26). This can mean injury from anything from mechanical compression to a demyelinating disease like MS. Classically, internal flow voids and presence of a large draining vein are seen; however, despite its high vascularity, associated hemorrhage is rare (42). The SI abnormality may be seen to extend cephalad along the corticospinal tracts into the intracranial compartment (50) (Fig 14). There is no mention of a herniated disc so I am unclear as to your surgeons reference to it. However, the prognostic significance of signal intensity changes remains controversial.
