Abstract
A 65-year-old woman with a resolved history of epilepsy due to a motor vehicle accident and hippocampal sclerosis presented with recurrent de novo seizures. Brain imaging demonstrated enhancement in the left parieto-occipital lobe. At histopathological examination, the lesion displayed a diffuse lymphoid infiltrate comprised of small atypical lymphocytes, plasmacytoid lymphocytes, and scattered plasma cells with amyloid deposition. Pathology workup demonstrated a monotypic B-cell phenotype of the lymphoid infiltrate, expressing lambda light chain restriction and plasmacytic differentiation without MYD88 mutations. The patient had no systemic evidence of lymphoma, plasma cell dyscrasia, or amyloidosis. A diagnosis of low-grade B-cell lymphoma of the central nervous system with plasmacytic differentiation and amyloid deposition was made.
期刊介绍：
Neuropathology is an international journal sponsored by the Japanese Society of Neuropathology and publishes peer-reviewed original papers dealing with all aspects of human and experimental neuropathology and related fields of research. The Journal aims to promote the international exchange of results and encourages authors from all countries to submit papers in the following categories: Original Articles, Case Reports, Short Communications, Occasional Reviews, Editorials and Letters to the Editor. All articles are peer-reviewed by at least two researchers expert in the field of the submitted paper.
