This case series describes the caudate body (CB) sign noted in computed tomography (CT) scans of patients who presented to the Emergency Department (ED) clinically manifesting symptoms suggestive of anterior cerebral circulation infarction. This sign has the advantage of early appearance, side-to-side comparison, and high conspicuity. Two of the presented cases demonstrate the CB sign in the absence of other established signs typically seen with early cerebral infarction. Five additional cases demonstrate this sign in conjunction with previously described criteria. The CB sign may allow earlier detection of hyperacute infarction leading to more rapid initiation of thrombolytics to minimize ischemic injury.
本病例系列描述了在急诊科就诊、临床表现提示大脑前循环梗死的患者计算机断层扫描（CT）中发现的尾状核体（CB）征。该征象具有出现早、可进行双侧对比以及辨识度高的优点。所呈现的两个病例显示，在没有早期脑梗死常见的其他既定征象的情况下出现了CB征。另外五个病例显示该征象与先前描述的标准同时出现。CB征可能有助于更早地检测超急性梗死，从而更迅速地启动溶栓治疗，以将缺血性损伤降至最低。
