title: [Primary cerebral lymphoma in an immunocompetent patient].
abstract: Primary lymphoma of the central nervous system PLCNS) was a very uncommon disease until a few decades ago. However, its incidence has increased in recent years, mainly in immunocompetent patients. Thus, some authors suggest that PLCNS may become the most frequent tumor. The final diagnosis is based on the pathology study of the samples obtained with stereotaxic biopsy or with surgery, but X-ray studies may be very useful in the orientation of this disease. The typical finding in immunocompetent subjects is the appearance of single supratentorial lesions with homogeneous uptake of contrast and scarce edema, without edema, necrosis nor bleeding. Survival has increased thanks to the new treatments applied, although there is still controversy regarding frequency, dose and administration form of many of them. We present the case of an immunocompetent male patient with progressive dyplopia and vertigo caused by a primary lymphoma of the central nervous system and a review the literature.
