ObjectiveTo report a case of marginal zone MALT lymphoma of the temporal dura mater, initially mistaken for temporal meningioma.Case reportA 60-year-old immunocompetent woman, followed for more than 10 years for temporal meningioma causing vertigo and mixed hearing loss, presented with cervical lymphadenopathy, revealing marked progression of an intracranial lesion, leading to a diagnosis of marginal zone MALT lymphoma based on histological examination of a cervical lymph node. Treatment with 6 cycles of rituximab and bendamustine allowed complete remission of cervical lymph node and intracranial lesions, confirming the diagnosis of temporal dural mater lymphoma.ConclusionPrimary dural lymphoma must be part of the differential diagnosis of meningioma. Long-term follow-up allows correction of the diagnosis.
