摘要

环礁标志,也被称为反向光环标志(RHS),由中心磨砂玻璃不透明的边缘包围而成。它最初是在组织性肺炎的背景下描述的,现在被认为是在一系列疾病中——包括感染性、炎症性、血管性、恶性和创伤性病理。这篇图片文章探讨了在急诊CT上观察到RHS的各种临床情况,强调了它在鉴别诊断和患者管理中的关键作用。

The reverse halo sign in emergency chest CT: A diagnostic guide across diverse pulmonary conditions.

The atoll sign, also known as the reverse halo sign (RHS), is defined by a central ground-glass opacity encircled by a rim of consolidation. Originally described in the context of organizing pneumonia, it is now recognized across a spectrum of conditions-including infectious, inflammatory, vascular, malignant, and traumatic pathologies. This pictorial essay examines the various clinical scenarios in which the RHS is observed on emergency CT, highlighting its crucial role in differential diagnosis and patient management.
