Multifocal regions of the cord demonstrate signal abnormality with increased T2 cord signal, cord expansion and enhancement.
At T10/T11 the spinal cord is expanded with 4.2cm length of vivid contrast-enhancement and a much greater extent of T2 hyperintensity. Incompletely imaged expansile and T2 hyperintense lesion at the cervicothoracic junction.
Multiple low T1 signal and enhancing lesions within vertebra: T2, T6 body, T9 body, T10 body, 2 in T11 body, T12 body, inferior endplate L1, superior end plate and spinous process L2, inferior end plate L4. Filling the spinal canal at S2 is contrast-enhancing lesion, which is hypointense on T2 to CSF, and is consistent with drop metastases.
Distal to this are prominent Tarlov cysts. Conus terminates at L1.
Conclusion: Multifocal, enhancing lesions within the cord with associated cord expansion, most consistent with tumour infiltration. In the setting of lymphoma this is consistent with secondary CNS lymphoma.
