概括
抗中性粒细胞质抗体 (ANCA) 相关的血管炎可以呈现为异常间歇性肺炎 (IIPs). 这项研究在高分辨率计算机断层扫描 (HRCT) 或骨髓氧化酶 (MPO) -ANCA和蛋白酶3 (PR3) -ANCA阳性IIP之间的病理发现中没有发现显著差异.
科学领域:
- 肺部病理学 肺部病理学
- 免疫学 免疫学 免疫学
- 放射学 放射学是一门学科.
背景情况:
- 抗中性粒细胞质抗体 (ANCA) 血清阳性与ANCA相关的血管炎有关.
- 异形间歇性肺炎 (IIPs) 即使没有全身性血管炎,也可能是ANCA阳性.
- 骨髓氧化酶 (MPO) -ANCA和蛋白酶3 (PR3) -ANCA阳性IIP之间的放射和病理发现的差异尚未得到充分理解.
研究的目的:
- 调查MPO-ANCA阳性和PR3-ANCA阳性IIP患者之间的高分辨率计算机断层扫描 (HRCT) 特性和病理发现是否不同.
- 从国家数据库中分析临床,放射和病理学数据.
主要方法:
- 审查了19名ANCA阳性IIP (10名MPO-ANCA,9名PR3-ANCA) 患者的记录,这些患者接受了HRCT和手术肺活检.
- 肺病学家,放射学家和病理学家对HRCT扫描和病理发现的独立评估.
- 使用ATS/ERS/JRS/ALAT 2011指南对异常性肺纤维化病的模式的分类.
主要成果:
- 在MPO-ANCA阳性和PR3-ANCA阳性IIPs之间没有观察到HRCT或病理模式的显著差异.
- 常见的HRCT特征包括网状 (68.4%),结节 (63.1%),蜂 (52.6%).
- 主要的病理发现是囊 (63.1%),带有生殖中心的淋巴卵泡 (57.9%) 和周围支气管淋巴细胞透 (57.9%).
结论:
- 在MPO-ANCA阳性和PR3-ANCA阳性IIP之间,HRCT和病理模式没有显著差异.
- 类似的发现表明,这些ANCA阳性IIP的共同底层机制.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
78
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...
