概括
当大脑活检显示死亡性颗粒瘤时,神经样症的诊断是具有挑战性的. 这项研究强调了神经类病,即使有死特征,也可以通过免疫抑制来诊断和有效治疗.
科学领域:
- 神经学 神经学
- 免疫学 免疫学 免疫学
- 病理学 病理学 病理学
背景情况:
- 神经类瘤 (NS) 诊断通常需要非死性颗粒瘤和结核病的排除.
- 活检上的死颗粒瘤可以模仿结核病,使NS诊断复杂化,特别是在没有系统参与的情况下.
研究的目的:
- 报告两例神经类瘤病例,中枢神经系统中呈现了死性颗粒瘤.
- 强调与非典型组织学发现有关的神经类病的诊断挑战和治疗考虑.
主要方法:
- 两名患有神经症状和中枢神经系统病变,暗示NS的患者的病例报告.
- 对大脑活检的组织病理学检查显示了死颗粒瘤.
- 通过阴性菌根菌培养和PCR排除结核病.
- 对抗中性粒细胞质抗体 (ANCA) 的评估.
- 对实证抗结核治疗和随后的免疫抑制疗法的反应.
主要成果:
- 两位患者都出现了与NS一致的神经症状和中枢神经系统病变.
- 脑部活检显示了死颗粒瘤,最初模仿结核病.
- 获得了微生物学和ANCA负结果.
- 对抗结核病治疗缺乏反应,导致考虑结核性沙体粒症 (NSG).
- 通过免疫抑制治疗实现了持续缓解,支持最终诊断NS.
结论:
- 中枢神经系统中的死角性颗粒瘤,即使模仿结核病,也不应该排除神经类病的诊断.
- 仅限于中枢神经系统的死角性类粒状瘤可能是神经类症的一个模式.
- 免疫抑制疗法对中枢神经系统的NSG是有效的,这强调了在微生物和免疫学发现负面的情况下考虑NS的重要性.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:22Bacterial Meningitis I: Introduction
31
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

01:26Bacterial Meningitis II: Pathophysiology
45
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

01:26Encephalitis ll: Pathophysiology
30
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...

01:26Brain Abscess l: Introduction
47
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...
