摘要

一名 75 岁的男子出现认知能力下降、头痛和共济失调步态。磁共振成像（MRI）显示多个脑区出现急性梗死，血管壁磁共振成像（VW-MRI）显示一些颅内动脉的动脉壁同心增厚和增强，初步提示为原发性中枢神经系统血管炎（PCNSV）。尽管接受了免疫抑制治疗，但患者仍出现了进一步的脑梗塞。皮肤活检发现了血管内大 B 细胞淋巴瘤（IVLBCL），尸检发现动脉壁上的肿瘤细胞与 VW-MRI 发现一致。本病例强调了仅凭影像学检查结果误诊 PCNSV 的风险，并强调了组织学确诊的必要性。

Vessel Wall Magnetic Resonance Imaging Showing Intravascular Large B-cell Lymphoma Infiltration: Association with Pathological Findings.

A 75-year-old man presented with cognitive decline, headaches, and ataxic gait. Magnetic resonance imaging (MRI) revealed acute infarcts in multiple brain regions, and vessel wall MRI (VW-MRI) demonstrated concentric arterial wall thickening and enhancement in some intracranial arteries, initially suggesting primary central nervous system vasculitis (PCNSV). Despite immunosuppressive therapy, the patient developed further infarction. A skin biopsy revealed intravascular large B-cell lymphoma (IVLBCL), and autopsy revealed tumor cells in the arterial walls corresponding to the VW-MRI findings. This case highlights the risk of a misdiagnosis of PCNSV based solely on imaging findings and underscores the need for histological confirmation.
