Primary dural lymphomas are very rare tumors—usually low-grade B-cell lymphomas of mucosa-associated lymphoid tissue type or marginal zone B-cell lymphomas. Primary dural involvement by diffuse large B-cell lymphoma is extremely rare, with only a few cases reported in the literature. The authors present an unusual case of primary dural involvement by a high-grade diffuse large B-cell lymphoma that presented as an acute subdural space-occupying mass and required emergency neurosurgical intervention.
Abbreviations used in this paper: DLBCL = diffuse large B-cell lymphoma; MALT = mucosa-associated lymphoid tissue; NHL = non-Hodgkin lymphoma; PCNSL = primary CNS lymphoma; SLE = systemic lupus erythematosus.
