放射性核素肝扫描已成为肝占位性病变诊断的重要手段。但有些肝外肿块,特别是腹膜后肿瘤,当压迫肝脏达一定程度时,可影响肝实质对放射性核素的摄取,而出现不同程度的缺损;或推挤肝脏使之移位或变形,改变了肝脏正常的几何投影,致图形识别困难,导致错误判断。本文报告我院1976年以来286例各种类型的肝占位性病变手术中,发现13例腹膜后肿瘤肝扫描误诊为肝占位性病变的资料。分析这些病例,试图找出一些规律性变化,以指导今后的工作。
Radionuclide liver scans have become an important diagnostic tool for liver-occupying lesions. However, some extrahepatic lumps, especially retroperitoneal tumors, can affect the uptake of radionuclides in the liver parenchyma when the liver is compressed to a certain degree, and have different degrees of defects; or push the liver to displace or deform, and change. The normal geometric projection of the liver caused difficulty in pattern recognition and led to wrong judgments. This article reports 286 cases of liver-occupying lesions of various types since 1976 in our hospital. 13 cases of retroperitoneal liver scans were misdiagnosed as liver-occupying lesions. Analyze these cases and try to find some regular changes to guide future work.
