Abstract

Purpose/aim

Lymphomatosis cerebri (LC) and cauda equina lymphoma are both rare forms of primary central nervous system lymphoma (PCNSL). LC is characterized by diffuse bilateral non-enhancing (or partially enhancing) inltrative lesions without mass effect, which can be easily confused with other forms of leukoencephalopathy and, thus, lead to delays in diagnosis.

Case report

For the first time, a case of LC concomitant with cauda equina involvement confirmed by brain stereotactic biopsy is presented.

Conclusions

This case highlights the necessity of using a multimodal strategy in diagnosing PCNSL, including multimodal magnetic resonance, cerebral spinal fluid cytology, flow cytometry and fluorodeoxyglucose positron emission tomography/computed tomography.

脑淋巴瘤伴马尾淋巴瘤

摘要

目的/目的

脑淋巴瘤 (LC) 和马尾淋巴瘤都是罕见的原发性中枢神经系统淋巴瘤 (PCNSL)。LC 的特点是双侧弥漫性非增强（或部分增强）浸润性病变，无占位效应，很容易与其他形式的白质脑病混淆，从而导致诊断延误。

案例报告

首次提出一例经脑立体定向活检证实的 LC 伴马尾受累。

结论

该病例强调了使用多模式策略诊断 PCNSL 的必要性，包括多模式磁共振、脑脊髓液细胞学、流式细胞术和氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描。
