title: [Primary dural lymphoma. A case report].
abstract: Primary central nervous system lymphoma is an invasive disease in both HIV-positive and HIV-negative patients. Atypical presentations, including leptomeningeal involvement often described in cases with aggressive histology, have been reported but primary meningeal B-cell lymphoma appears to be very rare. A 40-year-old immunocompetent man developed a voluminous frontoparietal cranial vault tumor. The neurology examination demonstrated a large extra-axial mass involving the anterior part of the superior longitudinal sinus. The tumor extended through the cranial vault, without osteolysis, and grew in the subcutaneous tissue. Craniotomy was performed and the entire mass was resected without neurological deterioration. Pathology reported B-cell lymphoma. No other localization was found. Primary B-cell meningeal lymphoma, as illustrated in this case, can be another atypical presentation of CNS lymphoma.
