概括

视网膜血管病变与大脑白脑病变 (RVCL) 是一种罕见的遗传疾病. 早期诊断至关重要,以避免误诊和不必要的治疗,如免疫疗法.

科学领域:

遗传学遗传学是一个
神经学神经学
眼科医生眼科眼科

背景情况:

视网膜血管病变与大脑白脑病变 (RVCL) 是一种罕见的自体主导遗传疾病.
它是由TREX1基因突变引起的,影响中枢神经系统 (CNS) 和其他器官.
由于相似的成像发现,RVCL经常被误诊为脱髓化或血管炎,导致潜在的有害治疗.

研究的目的:

描述两位患有RVCL的姐妹表现为半衰减,视网膜血管病变和肝功能障碍.
突出诊断挑战和在非典型的神经病例中基因检测的重要性.

主要方法:

两位受影响的姐妹的临床病例报告.
神经成像 (MRI) 来评估白质病变.
基因分析以确定TREX1基因中的突变.
排除自身免疫和传染病的原因.

主要成果:

两名患者均呈现出进展性半衰竭,视网膜血管病变和肝功能障碍.
神经成像显示了广泛的,不对称的白质病变,与扩散限制和对比度增强.
遗传分析在两位姐妹的TREX1基因中发现了一种新的异质合体变异,证实了RVCL的诊断.
一位姐姐最初被误诊并接受了脑血管炎治疗.

结论:

在疑似脱髓化或中枢神经系统血管炎的非典型表现的患者中应考虑RVCL.
通过基因检测进行准确的诊断对于指导适当的管理和避免不必要的免疫治疗至关重要.
TREX1基因突变是RVCL病变的一个关键因素.

Encephalitis l: Introduction

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Cerebral Edema ll: Pathophysiology

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...
