Primary cerebellar B cell lymphoma: A case report

Abstract

Introduction: Primary central nervous system lymphoma (PcNsL) is usually a diffuse large b cell non-Hodgkin lymphoma that originates in the brain, spinal cord, leptomeninges or eyes. Primary central nervous system lymphoma is a rare malignant tumor comprising less than 3% of all primary brain tumors. the PcNsL in immunocompetent patients is most commonly supratentorial, found adjacent to the ventricular surfaces and in deep white matter and subcortical structures, such as the basal ganglia, thalamus and corpus callosum. the lesion is single in 60-70% of patients. Lesions are located in the hemispheres (38%), thalamus/basal ganglia (16%), corpus callosum (14%), periventricular region (12%) and cerebellum (9%). Herein, we report an extremely rare case of a primary cNs b cell lymphoma involving cerebellum. case report: A 55-year-old female was presented with vomiting, ataxia and disorientation. t2
