It is sometimes difficult to differentiate focal nodular hyperplasia from other hepatic tumors. A report is presented of a patient in whom three-dimensional computed tomography was useful to diagnose focal nodular hyperplasia of the liver. In a 31-year-old women with epigastralgia, ultrasonography and computed tomograms showed a tumor in the liver. Three-dimensional computed tomograms showed a hypervascular lesion with a hypodense interior and feeding arteries on early images. On delayed images, a draining vein connecting with the hepatic vein was clearly demonstrated. Although focal nodular hyperplasia was strongly suspected, the tumor was resected because of the enlargement and extrahepatic growth of the tumor. Pathologic examination showed that the tumor was focal nodular hyperplasia of the liver. A draining vein connecting to the hepatic vein may be a characteristic of focal nodular hyperplasia. Three-dimensional computed tomography may be useful to diagnose focal nodular hyperplasia of the liver.
有时很难将局灶性结节性增生与其他肝脏肿瘤区分开来。本文报告了一例患者，三维计算机断层扫描对诊断肝脏局灶性结节性增生很有用。一名31岁有上腹部疼痛的女性，超声检查和计算机断层扫描显示肝脏有一个肿瘤。三维计算机断层扫描显示在早期图像上有一个内部低密度的高血管病变和供血动脉。在延迟图像上，清晰显示了一条与肝静脉相连的引流静脉。尽管强烈怀疑是局灶性结节性增生，但由于肿瘤增大并向肝外生长，该肿瘤被切除。病理检查显示该肿瘤为肝脏局灶性结节性增生。与肝静脉相连的引流静脉可能是局灶性结节性增生的一个特征。三维计算机断层扫描可能有助于诊断肝脏局灶性结节性增生。
