Intracranial malignant B-cell lymphoma of the dura

Objective: Malignant B-cell lymphomas of the dura mater are very rare. A ca se of primary centroblastic/centrocytic lymphoma of the dura mimicking a bi lateral convexity meningioma is presented. Clinical presentation: A 50-year -old woman was referred to our institution with a 6-month history of headac he and two Jacksonian seizures. Computed tomography revealed a parafalcine and bilateral convexity lesion. Cerebral angiography and magnetic resonance imaging were performed prior to surgery. At surgery the tumor was removed subtotally. The patient was treated postoperatively by combined chemo- and radiotherapy. Conclusion: Laboratory studies and follow-up examinations rev ealed no evidence of systemic lymphoma nor of any immunocompromized state. According to the presented case combined surgery and chemoradiotherapy seem s to be an effective treatment for this rare lesion.
