Intravascular lymphoma (IVL) is an aggressive systemic large B-cell lymphoma that is a rare cause of stroke. The clinical characteristics of stroke associated with IVL remain underexplored, contributing to diagnostic complexities and a high mortality rate. This study endeavors to elucidate the salient clinical and investigative features of stroke linked to this condition. A systematic review was performed using the PubMed database from the incident to August 2023 including search categories for IVL and stroke. All studies, excluding review articles, were included in this study. There were 58 cases with a confirmed diagnosis of IVL associated with stroke, with a mean age of 62.9 ± 9.6 years (female 50%). Classical lateralizing stroke symptoms were noted in only 69% of cases. Other clinical syndromes included altered sensorium (31%), rapidly progressive cognitive impairment (23%), seizures (22%), and gait disturbances (19%). Common hematological abnormalities included elevated lactate dehydrogenase (LDH, 97%), erythrocyte sedimentation rate (ESR, 79%), C-reactive protein (CRP, 61%), interleukin-2, microglobulins, and cerebrospinal fluid (CSF) protein. CSF flow cytometry was not diagnostic, and cytology was mostly negative. The dynamic pattern for DWI/T2 lesions was predominant and primarily located in the subcortical regions. Diffuse background slowing (64%) was a major finding in the electroencephalogram. Seventy-one percent of cases died (n=45) mostly due to delayed diagnosis. Only 31% were treated with first-line R-CHOP (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, prednisone) chemotherapy, among whom 25% died. This study suggests that IVL-associated strokes carry a high mortality rate, largely due to challenges in timely diagnosis and therapy. Unlike classical stroke syndrome, key indicators to aid in early diagnosis include a clinical syndrome of multiple non-lateralizing neurological symptoms, dynamic MRI DWI/T2-lesions primarily located in subcortical regions, elevated serum LDH, ESR, CRP, interleukins, microglobulin, CSF protein, and CSF polymerase chain reaction analysis, apart from tissue examination. Larger studies should be performed to establish diagnostic and predictive scores.
血管内淋巴瘤(IVL)是一种侵袭性全身性大B细胞淋巴瘤,是导致中风的罕见病因。与IVL相关的中风的临床特征仍未得到充分研究,这导致诊断复杂且死亡率高。本研究旨在阐明与这种情况相关的中风的显著临床和检查特征。使用PubMed数据库进行了一项系统评价,时间范围从发病至2023年8月,搜索类别包括IVL和中风。本研究纳入了所有研究(不包括综述文章)。共有58例确诊为与中风相关的IVL病例,平均年龄为62.9±9.6岁(女性占50%)。仅69%的病例出现典型的局灶性中风症状。其他临床综合征包括意识改变(31%)、快速进展的认知障碍(23%)、癫痫发作(22%)和步态障碍(19%)。常见的血液学异常包括乳酸脱氢酶升高(LDH,97%)、红细胞沉降率(ESR,79%)、C反应蛋白(CRP,61%)、白细胞介素-2、微球蛋白和脑脊液(CSF)蛋白。脑脊液流式细胞术无诊断价值,细胞学检查大多为阴性。DWI/T2病变的动态模式为主,主要位于皮质下区域。脑电图的主要发现是弥漫性背景减慢(64%)。71%的病例死亡(n=45),主要原因是诊断延迟。只有31%的病例接受了一线R-CHOP(利妥昔单抗、环磷酰胺、盐酸多柔比星、长春新碱、泼尼松)化疗,其中25%死亡。本研究表明,与IVL相关的中风死亡率很高,主要是由于及时诊断和治疗方面存在挑战。与经典中风综合征不同,有助于早期诊断的关键指标包括多种非局灶性神经症状的临床综合征、主要位于皮质下区域的动态MRI DWI/T2病变、血清LDH、ESR、CRP、白细胞介素、微球蛋白、CSF蛋白升高以及CSF聚合酶链反应分析,除了组织检查。应进行更大规模的研究以建立诊断和预测评分。
