spinal cord metastasis

Presumed spinal cord metastasis in a female patient known to have breast cancer. MRI shows:
– Focal cord expansion with intramedullary enhancing mass,
– Thin enhancing rim along lower anterior cord surface and,
– Enhancing metastatic foci in the bone marrow.

Spinal cord metastases can be:
1-Intramedullary (within the cord): rare.
2-Pial (Superficial, along pial surface): in most of the cases.

Common primary CNS tumors: PNET/medulloblastoma and glioblastoma.
Common primary malignancy outside CNS: lung (70%), breast (11%), melanoma, kidney, lymphoma and leukemia.
