Early ischemic changes seen on Non-contrast computed tomography (NCCT) secondary to cerebral edema is believed to indicate irreversible cellular injury. Computed tomography perfusion (CTP) may overpredict the infarct core in patients with large vessel occlusion (LVO) presenting in acute phase as these changes are potentially reversible if successful endovascular reperfusion is performed in a timely manner. This has led to the concept of "ghost infarct core" which is the mismatch in the infarct core as seen on follow-up imaging. We present a case which potentially supports the concept of "ghost infarct core" evaluated not only by CTP but also NCCT in a patient with LVO following successful thrombectomy.
非增强计算机断层扫描（NCCT）上所见的继发于脑水肿的早期缺血性改变被认为提示不可逆的细胞损伤。计算机断层扫描灌注（CTP）可能会高估急性期出现大血管闭塞（LVO）患者的梗死核心，因为如果及时进行成功的血管内再灌注，这些改变可能是可逆的。这就引出了“幽灵梗死核心”的概念，即随访成像中所见梗死核心的不匹配情况。我们报告一例成功进行血栓切除术后的LVO患者，该病例不仅通过CTP，而且通过NCCT评估，可能支持“幽灵梗死核心”的概念。
