Sagittal MRI T2-weighted demonstrating an intramedullary mass spanning T6 to T11. The mass measures 7.8 × 1.4 × 1.5 cm and is the largest in diameter at the T8 level where it demonstrates considerable cerebrospinal fluid effacement. There is no associated syrinx. Post gadolinium contrast imaging (not shown) shows patchy enhancement, most evident in the inferior aspect of the lesion.
