Dural marginal zone lymphoma with massive amyloid deposition: rare low-grade primary central nervous system B-cell lymphoma - Case report JOURNAL OF NEUROSURGERY Lehman, N. L., Horoupian, D. S., Warnke, R. A., Sundram, U. N., Peterson, K., Harsh, G. R. 2002; 96 (2): 368-372


The authors report the case of a 63-year-old woman who presented with a primary dural extranodal marginal zone lymphoma (MZL) associated with massive kappa light chain amyloidosis of the meninges. Extranodal MZL is a low-grade B-cell lymphoma that may show variable degrees of plasmacytic differentiation. Like solitary plasmacytoma of soft tissue, which can also be associated with amyloid, extranodal MZL generally responds well to local therapy and has a good prognosis. It is important to distinguish these entities from high-grade primary central nervous system (CNS) B-cell lymphomas and more aggressive and/or widespread, potentially amyloidogenic conditions such as multiple myeloma, lympho-plasmacytoid lymphoma, and chronic lymphocytic leukemia/small lymphocytic lymphoma. To the authors' knowledge this is the first reported case of dural MZL associated with massive meningeal amyloid deposition. Extranodal MZL is a rare low-grade primary CNS B-cell lymphoma that may be associated with amyloidosis. It should be considered in the differential diagnosis of CNS lymphoproliferative lesions and CNS amyloidosis.
