 There is an intramedullary abnormality within the cervical cord at the level of C6/7. It is slightly expansile, T1 hypointense, T2 hyperintense, measuring 5 mm transverse x 4 mm AP x 11 mm craniocaudal dimension.Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable. There are no significant degenerative changes and there are no stenoses.
There is an intramedullary abnormality within the cervical cord at the level of C6/7. It is slightly expansile, T1 hypointense, T2 hyperintense, measuring 5 mm transverse x 4 mm AP x 11 mm craniocaudal dimension. Given this constellation of features, this most likely represents a small syrinx, and other T2 hyperintense etiologies such as inflammatory or neoplastic processes are felt to be less likely. However, contrast enhancement is recommended to further characterize the lesion.
