Primary leptomeningeal lymphomas are rare, and usually follow a rapid clinical course with early systemic involvement. A 60-year-old woman presented with a 3-year history of worsening seizures and memory loss. Neuroimaging showed widespread meningeal calcification. After extensive investigations a meningeal biopsy revealed a low-grade B-cell lymphoma categorized as an extranodal marginal zone B-cell lymphoma, attributed to the same histological group as the MALT (mucosa-associated lymphoid tissue) lymphomas described in the stomach, thyroid, salivary glands and orbit. There was no evidence of systemic involvement. The extensive meningeal calcification would appear to be a novel finding in primary leptomeningeal lymphoma whereas the unusually long clinical history in this case is possibly related to the particular histological type of low-grade B-cell lymphoma.

Primary indolent leptomeningeal lymphoma is a rare entity, and corresponds in most cases to mucosa-associated lymphoid tissue (MALT) type lymphoma. We are reporting a case of a 75 years old woman, who presented with a 2-year history of behavioral disorder, progressive memory loss and aphasia. Neuroimaging showed a mass infiltrating the frontal circumvolutions and the roof of the orbit. The biopsy revealed an infiltration of the dura by an indolent lymphoma, characteristic of a MALT-type lymphoma. Complete staging work-up did not show any evidence of systemic involvement. A treatment with systemic methotrexate, combined with intrathecal chemotherapy and followed by radiotherapy (30,6 Gy) of the primary site, was conducted. The 3-year follow-up confirms the persistent remission, the patient remaining well and free of symptoms. The review of the literature highlights the importance to recognize the indolent PLML as a distinct clinical entity, which exhibits a rather good prognosis following a relatively non-toxic therapy.
