[Primary multicentric cerebral lymphoma in a previously healthy patient]. / Linfoma cerebral primario multicéntrico en paciente previamente sano.

Primary cerebral non-Hodgkin's lymphoma (PCL) is not very frequent, especially in the immunologically normal patient. Its radiological features and the response to steroid and radiotherapy treatment force the physician to consider it amongst the differential brain tumor diagnoses; particularly when an extraordinary remission is observed after steroid treatment, even in an immunologically normal patient.
