概括

支气管中心型颗粒瘤 (BCG) 在CT和PET扫描上可以呈现出不寻常的扩散性肺部图案. 这种罕见的疾病可能会模仿恶性瘤,强调需要仔细的放射学解释.

科学领域:

肺部病理学肺部病理学
放射学放射学是指放射学
病理学病理学病理学

背景情况:

支气管中心颗粒瘤症 (BCG) 是一种罕见的以呼吸道为中心的颗粒瘤性疾病.
BCG被认为是一种免疫媒介的过程,而不是一种活跃的感染.
图像BCG的发现通常是非特异性的,可以模仿肺癌或感染.

研究的目的:

报告一个不常见的BCG呈现与扩散的网状模不透明.
为了突出[18F]FDG-PET/CT在诊断BCG时的实用性.
提高对非典型BCG成像特征的认识.

主要方法:

一个63岁的妇女的病例报告,患有持续发烧和扩散的肺不透明.
使用胸部计算机断层扫描 (CT) 和[18F]FDG-PET/CT进行成像.
进行支气管镜检查和手术肺活检以诊断.

主要成果:

胸部CT显示了扩散的双边网膜模不透明.
[18F]FDG-PET/CT揭示了无肺外疾病的扩散性肺吸收.
手术活检证实了支气管中心颗粒状炎症.

结论:

BCG可以呈现出模仿恶性瘤的扩散性,代谢活跃的肺病.
在BCG中非典型的成像发现需要考虑,特别是不确定的微生物学结果.
放射科医生应该了解在扩散性肺病中BCG的各种表现.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

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...
