摘要

摘要：在造影剂增强 CT 或 MR 图像中，肝脏假性肿块比较常见，这归因于独特的肝内血流动力学。此外，放射性核素肝脏扫描中的异常侧支循环也可能导致局灶性肝摄取。本报告介绍了一例通过 FDG PET/CT 发现的肝脏扇形高代谢病例，该病例与造影剂增强胸部 CT 上观察到的肝脏衰减增加区域相关，该患者患有肺癌，且并发上腔静脉阻塞。值得注意的是，改变示踪剂注射途径后，2 天后进行的 FDG PET/CT 成像检查发现，非生理性高代谢活动已经消失。

Sectorial Hypermetabolic Pseudolesion in the Liver on FDG PET/CT Caused by SVC Obstruction.

Abstract: Hepatic pseudolesions are relatively frequent in contrast-enhanced CT or MR images, attributable to the unique intrahepatic hemodynamics. It is also well documented that focal liver uptake can result from unusual collateral circulation on radionuclide liver scans. This report presents a case of sectorial hepatic hypermetabolism identified via FDG PET/CT, correlating with areas of increased attenuation in the liver observed on contrast-enhanced chest CT in a patient with lung cancer complicated by superior vena cava obstruction. Notably, the nonphysiological hypermetabolic activity was resolved on subsequent FDG PET/CT imaging conducted 2 days later, following alteration of the tracer injection route.
