概括
腹腔内皮洛细胞性星形细胞瘤 (PAs) 呈现出头痛和动力衰竭等常见症状. 高显微扩散系数 (ADC) 值可以帮助诊断这些罕见的成年瘤.
科学领域:
- 神经瘤学神经瘤学
- 儿科神经外科 儿科神经外科
- 神经辐射学神经辐射学
背景情况:
- 皮洛细胞性星细胞瘤 (PAs) 通常是中线瘤,但也观察到心室内部位.
- 腹腔内PAS虽然在儿科患者中更常见,但在成年人中也可能发生.
研究的目的:
- 详细介绍16名患有腹腔内皮洛细胞天体瘤 (PAs) 的患者的临床和成像特征.
- 为了分析表面扩散系数 (ADC) 值与心室内PAS的关系.
主要方法:
- 对16名被诊断患有腹腔内PAS的患者的回顾性分析 (2016年2月 - 2022年1月).
- 评估临床表现,成像发现和ADC测量.
主要成果:
- 该队列包括8名男性和8名女性,平均年龄为20.8岁.
- 头痛和动力衰竭是最常见的症状. 损伤平均为48.19毫米,其中56.2%位于第四心室.
- 与体/白质相比,心室内PAS的ADC值显著更高 (1.57 × 10−3 mm2/s) (p < 0.001).与体/白质相比,心室内PAS的ADC值显著更高 (1.57 × 10−3 mm2/s).
结论:
- 腹腔内PAS虽然比中线PAS少,但在差异诊断中需要考虑.
- 升高的ADC值是考虑PAS在内腔瘤差异诊断中的关键指标,即使在成年人中也是如此.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
