Lymphoma of a dural genesis is a distinct variant of primary central nervous system lymphoma and is rare. It putatively has a more benign clinical course. Cranial primary dural lymphoma is more often marginal zone B-cell lymphoma, whereas spinal primary dural lymphoma is most commonly diffuse large B-cell lymphoma.
We report a male patient who presented with subacute progressive radiculopathy due to a compressive infiltrative lumbosacral spinal lesion. This was determined to be primary dural diffuse large B-cell lymphoma. The radiology, therapeutic considerations and differentiating biological characteristics of primary dural lymphoma, differ from other primary central nervous system lymphomas.
Primary dural lymphoma is under-represented in the medical literature. It has unique clinical characteristics. The optimal treatment algorithm remains undefined, but there is some evidence suggesting a benefit of surgical cytoreductive therapy in the first instance, and low-dose radiotherapy may be an effective adjuvant therapy in addition to chemotherapeutic and immunotherapeutic agents.
