Longitudinally extensive cord signal T2 abnormality extends from the conus to the level of T6. The conus is expanded, with high T2 signal and 4mm ovoid faintly rim enhancing intra medullary lesion at the level of T11/12. The lesion demonstrates low T2 signal rim, particularly on the right. Patchy linear enhancement within the cord to the right just above this level is evident. There is enhancement of nerve roots at this level.
Left posterior parafalcine meningeal mass is noted. Optic nerves appear unremarkable. Appearances elsewhere are unremarkable.
Conclusion:
Conus is expanded with an intra medullary rim enhancing lesion centred at the level of T11/12 with further surrounding enhancement over the surface of the cord. Differential remains includes a primary cord mass lesion such as a tumour ( primary or secondary - dural intracranial mass probably represents a meningioma but could also be another secondary deposit) cavernoma, sarcoid or atypical infection. Given the presence of a focal mass lesion, inflammatory entities such as NMO and post infectious myelitis are also possible.
