Abstract
A primary central nervous system lymphoma is a form of extranodal disease originating in the brain, leptomeninges, spinal cord, or eyes. Spinal tumors are low-prevalence neoplasms and can cause considerable neurological morbidity and mortality. An isolated lymphoma emerging within the dural canal is the rarest form of primary central nervous system lymphoma: it accounts for approximately 1% of cases occurring more often in the context of secondary dissemination than as the primary site of origin. Symptoms are nonspecific and depend on the spinal level involved. The presentation is insidious and includes dorsalgia, weakness, and progressive difficulty in ambulatory function. MRI is the modality of choice to search for lesions within the spinal/rachial canal in patients presenting with neurological symptoms. Surgical treatment is not helpful, and the main objective of surgery is to know the histological diagnosis.
