MRI
The MRI sequences demonstrate an ill-defined eccentric intramedullary mass expanding the spinal cord from C2 to T1 (length of involvement is 7 vertebral body segments). It is of low signal intensity on T1WI, high signal intensity on T2WI, and STIR with areas of patchy enhancement on postcontrast sequences. No haemorrhagic component is seen. No posterior vertebral body scalloping or thinning of the pedicles.
