ABSTRACT

El linfoma primario del sistema nervioso central es una forma de enfermedad extraganglionar originada en el cerebro, la leptomeninges, la médula espinal o los ojos. Los tumores espinales son neoplasias de baja prevalencia y pueden causar una morbimortalidad neurológica considerable. El linfoma aislado que surge dentro del conducto dural es la forma menos común de linfoma primario del sistema nervioso central: representa aproximadamente el 1% de los casos y se observa más a menudo en el contexto de diseminación secundaria que como el sitio primario de origen. Los síntomas son inespecíficos y dependen del nivel espinal involucrado. La presentación es insidiosa e incluye dorsalgia, debilidad y dificultad progresiva para la deambulación. La resonancia magnética es la modalidad de elección para búsqueda de lesiones dentro del conducto espinal/raquídeo, en pacientes que presentan síntomas neurológicos. El tratamiento quirúrgico no resulta útil, y el objetivo principal de la cirugía es conocer el diagnóstico histológico. (AU)


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. (AU)
