Pulmonary Hypertension: Classification and Pathogenesis

543
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

科学领域:

  • 医疗成像医学成像
  • 病理学 病理学 病理学
  • 在瘤学瘤学.

背景情况:

  • 肺洞性血管瘤 (PCH) 异常罕见,由于无特异性放射性特征,经常被误诊为转移性瘤.
  • 本报告详细介绍了多个PCH病变与肝洞性血管瘤 (HCH) 同时发生的独特案例.

研究的目的:

  • 为了强调成像发现的诊断含义,在一个罕见的多重肺和肝洞性血管瘤的病例.
  • 讨论区分PCH与恶性肺病的挑战.

主要方法:

  • 一名57岁的男性发烧;CT显示多个肺结节和肝脏病变.
  • 进行了动态对比增强CT和PET-CT. 血清瘤标志物是正常的.
  • 肺部和肝脏活检的组织病理学检查证实了这两个器官中的洞穴性血管瘤.

主要成果:

  • 扫描图显示了大量的精确的肺结节和多个低密度的肝病变,具有特有的增强模式.
  • 在任何病变中,PET-CT没有显示任何异常的氧葡萄糖吸收.
  • 活检证实了洞穴性血管瘤,排除了恶性瘤.

结论:

  • PCH是一种罕见的良性瘤,具有模糊的成像特征,使得与转移性肺癌的差异化变得困难.
  • 虽然手术活检仍然是黄金标准,但像PET-CT上的微化和缺少FDG吸收等暗示性成像研究结果可以帮助诊断并可能避免侵入性手术.
