概括
磁共振成像 (MRI) 可以区分侵袭性真菌轨道感染 (IFOI) 和细菌轨道细胞炎 (OC). 对IFOI的关键MRI发现包括组织增强和侵入的特定模式,有助于早期诊断.
科学领域:
- 放射学 放射学是一门学科.
- 眼科医生 眼科 眼科
- 传染性疾病 传染性疾病
背景情况:
- 侵入性真菌轨道感染 (IFOI) 存在诊断挑战,通常模仿阴源性细菌轨道细胞炎 (OC).
- 准确的区分对于及时和适当的治疗至关重要,影响患者的治疗结果.
研究的目的:
- 识别和描述磁共振成像 (MRI) 的特征,区分IFOI与sinogenic OC.
- 为了提高诊断准确度,使用MRI来区分这两种轨道感染.
主要方法:
- 对已证实有阴源性OC或IFOI的成年患者进行了回顾性分析,这些患者接受了干预前的MRI.
- 统计分析 (独立样本的t测试,费舍尔的精确测试) 用于比较两个组之间的成像特征.
- 排除标准包括非阴源性OC,创伤相关病例和质量差的扫描.
主要成果:
- 与OC患者相比,IFOI患者年龄较大,免疫功能较弱,白细胞数量较低.
- 针对IFOI的显著MRI发现包括膨胀/质像轨道病变,鼻中对比增强损失 (LoCE) 和鼻外延伸.
- OC 病变通常是透性的和划界不良的,更频繁地涉及脑前部和眼腺.
结论:
- 特定的MRI特征,包括LoCE和连续软组织扩散的模式,是IFOI和OC之间的关键区别.

219
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...

32
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...

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...
