Primary dural lymphoma: a comprehensive literature review and report of a case

Primary dural lymphoma (PDL) is a subtype of primary central nervous system (CNS) lymphoma (PCNSL) with only an extra-axial dural location. It accounts for less than 1% of all CNS lymphomas. PDL is a sporadic CNS tumor, and in the preoperative period, because of imaging characteristics, it is usually mimicking a meningioma. Usually, PDL is a low-grade B-cell lymphoma with a relatively good response to surgical resection with or without radiotherapy. Here we reviewed 102 case reports of PDL in the literature. Then, we present the case of our patient with PDL and explain the complexity of our treatment approach
