title: [Masquerade syndrome in a patient with a primary central nervous syndrome lymphoma].
abstract: We report the case of a 37-year-old, white male with a primary central nervous system lymphoma with multiple supra and infratentorial locations. The patient developed manifestations of intraocular inflammation secondary to the intracranial neoplasm (masquerade syndrome) and lymphocytopenia--with a low CD4 cell count--representing an immunodeficiency state which etiology was undiagnosed. The diagnosis of lymphoma was established by vitreous cytology. The patient died 10 months after the beginning of the symptoms.
