概括

肺化颗粒瘤 (PHG) 是一种罕见的肺部疾病. 本案例研究详细介绍了外围肺病变的10年进展情况,最终在排除恶性病变后被诊断为PHG.

科学领域:

肺部病理学肺部病理学
病理学病理学病理学
放射学放射学是一门学科.

背景情况:

肺化颗粒瘤 (PHG) 是一种非常罕见的良性肺部疾病.
全球范围内记录的PHG病例不到200例.
PHG的病因仍然是未知的.

研究的目的:

介绍PHG的一个独特病例,观察期长达十年.
突出外周肺病变 (PPLs) 在PHG中所带来的诊断挑战.
为了说明先进的成像和活检在诊断PHG中的作用.

主要方法:

一名中年男性患者患有多种双边PPL,被监测了10年.
诊断工具包括胸部X射线,计算机断层扫描 (CT),氧糖-正子辐射断层扫描 (FDG-PET) 和活检.
进行了PPL的胸腔镜切除,以确定确诊.

主要成果:

患者出现了PPL,其规模和数量逐渐增加.
在病变中,FDG-PET揭示了异质的高代谢.
最初的转移怀疑被良性腺活检和非恶性肺活检排除了.
胸腔镜切除证实了肺部化颗粒瘤的诊断.

结论:

PHG可以呈现为多个双边的PPL,随着时间的推移,其大小和超高代谢率会增加.
包括成像和组织活检在内的综合诊断方法对于区分PHG与恶性疾病至关重要.
这一案例强调了在对肺病变的差异诊断中考虑罕见良性疾病的重要性.

Pulmonary Tuberculosis II

Pulmonary Tuberculosis II

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...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

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:
