2019年8月5日 · Acute fibrinous and organizing pneumonia (AFOP) is a very rare form of acute or subacute lung injury, which is characterized by patches of “fibrin balls” distributed within the alveoli. Given the lack of typical clinical manifestations, AFOP is often misdiagnosed as pneumonia, tuberculosis, etc. Definitive diagnosis is obtained from a lung ...

Acute fibrinous and organizing pneumonia (AFOP) is a unique pathological entity with intra-alveolar fibrin in the form of “fibrin balls” and organizing pneumonia. It was divided into rare idiopathic interstitial pneumonia according to the classification notified by American Thoracic Society/European Respiratory Society in 2013.

2022年2月8日 · Acute fibrinous and organizing pneumonia (AFOP) is a rare interstitial pneumonia characterized by intra-alveolar fibrin deposition and organizing pneumonia. The clinical manifestations and long-term prognosis of AFOP are unclear. Our objective was to investigate the clinical features and prognosis of AFOP.

Acute fibrinous and organizing pneumonia (AFOP) is an uncommon type of acute lung injury associated with infection, connective tissue disorders, drug exposure, and hematologic malignancies. A 53-year-old female presented with intermittent …

2021年3月3日 · AFOP is a rare idiopathic interstitial pneumonia with variable prognosis. Imaging findings are nonspecific and include ground-glass opacities and foci of organising pneumonia. The definitive diagnostic is histological, with identification of "fibrin balls" inside the alveoli and foci of organising pneumonia.

2021年3月31日 · Subacute indolent presentation and patchy or mass-like air-space consolidation at the presentation on CT images indicated a good prognosis in patients with AFOP. • Acute fibrinous and organizing pneumonia (AFOP) cases diagnosed via non-surgical biopsy had different symptomatic presentations and prognosis from surgically proven AFOP.

afop为急性或亚急性起病，不同于目前已知的任何一类间质性肺炎，主要病理表现为肺泡腔内纤维蛋白球以及机化的疏松结缔组织。 本研究中回顾性分析南京市鼓楼医院2011年3月至2012年6月诊治的5例AFOP患者的临床资料，并进行相关文献复习，以期提高临床医生对 ...

afop 的组织病理学表现为镜下肺泡腔内可见 大量纤维素性渗出物，其典型特点主要为：1)肺 泡腔内可见明显的广泛分布的“均质嗜酸性纤维 素球”样物质；2)与op改变相似，afop 的纤维素 球中几乎均具有不同程度的op表现；3)肺泡腔内

AFOP的胸部CT影像学特点主要为双侧弥漫性分布且以基底部为主的磨玻璃影或融合状斑片影。 其中急性起病、进展迅速的患者胸部CT影像表现与DAD类似，以基底部为主的实变和磨玻璃阴影为主要表现；而亚急性起病患者在胸部C T影像表现上与COP类似，最常见表现为双肺多发的、游走的、分布不均匀的弥漫磨玻璃影、斑片状实变影，以外周和双肺底分布为主；也可表现为沿支气管血管束周围分布的肺实变，在实变部位的支气管扩张、支气管壁增厚；双肺弥漫的粟粒样结节 …

The definitive diagnosis of AFOP relies on pathological evidence of intra-alveolar fibrin exudate, lymphoplasmacytic infiltrate, and the absence of a hyaline membrane.
