まとめ
N-メチル-D-アスパルテート受容体抗体脳炎 (NMDAR脳炎) は,主性中枢神経系リンパ腫 (PCNSL) と関連付けられる. この研究は,PCNSLがNMDAR脳炎の潜在的パラネオプラスティック原因であることを示唆する3つの症例を提示しています.
科学分野:
- 神経学
- 免疫学
- 腫瘍学
背景:
- N-メチル-D-アスパルテート受容体抗体脳炎 (NMDAR脳炎) は一般的な自己免疫疾患である.
- NMDAR脳炎症症例の約38%でパラネオプラスティック関係が確認されています.
- 主要な中枢神経系リンパ腫 (PCNSL) は,根本的な原因としてめったに考慮されません.
研究 の 目的:
- PCNSLに関連したNMDAR脳炎の3症例を報告する.
- これらの希少な状態の共存を示唆する臨床的特徴を特定する.
- NMDAR脳炎における潜在的パラネオプラスティック源としてPCNSLを強調する.
主な方法:
- NMDAR脳炎の疑いのある3人の患者が報告されました.
- 臨床データと診断結果をレビューした.
- 分析は,NMDAR脳炎とPCNSLとの関連に焦点を当てた.
主要な成果:
- PCNSL患者でNMDAR脳炎の3例が診断されました.
- 両方の状態の同時発生を示す特定の臨床的特徴が観察されました.
- PCNSLは,パラネオプラスティックな起源であると特定された.
結論:
- PCNSLは,自己免疫性脳炎,特にNMDAR脳炎の微分診断に考慮されるべきである.
- PCNSLとNMDAR脳炎の関連性を認識することで,診断と治療を改善することができます.
- この関連は,自己免疫神経疾患における潜在的パラネオプラスティック原因の調査の重要性を強調しています.

Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
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 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...
