Primary Dural Lymphoma: A Rare Case With Rapidly Growing Lesions and Successful Treatment Through Biopsy and Chemotherapy.

Primary dural lymphoma (PDL) is an exceptionally rare subtype of lymphoma restricted to the central nervous system. Owing to its lack of distinctive clinical symptoms and radiographic features, it often poses a diagnostic challenge, particularly in differentiating it from meningioma. Here, we report a case of malignant lymphoma in the left parietal region that rapidly enlarged and was difficult to diagnose. Magnetic resonance imaging (MRI) revealed a lesion extending from the subcutaneous region to the extradural and intradural regions. In cases of rapidly growing disease, lymphoma should be aggressively considered and preceded by a biopsy; this will appropriate chemoradiation with minimal surgical invasion.
