Primary hepatic actinomycosis is rare, and there have been few reports concerning its nuclear imaging findings. Two cases of actinomycosis, in which hypervascular hepatic masses were observed in the arterial phase of radionuclide angiography are reported. To the authors' knowledge, this finding has not been reported in the literature. In one of the two cases, intense Ga-67 uptake also was noted. Although the preoperative diagnosis based on the findings of nuclear imaging (liver scan, liver flow study, Ga-67 scan), ultrasound, CT, and angiography was hepatoma, hepatic masses in our cases proved to be hepatic actinomycosis. Because hepatic actinomycosis is rare, this disease is neglected often in the differential diagnosis of hepatic mass lesions. It should be included in the gamut of hypervascular hepatic mass lesions.
原发性肝放线菌病罕见，关于其核素显像表现的报道很少。本文报告两例放线菌病，在放射性核素血管造影动脉期观察到肝脏高血运肿块。据作者所知，该发现尚未见文献报道。两例中的一例还观察到镓-67摄取增强。尽管根据核素显像（肝脏扫描、肝脏血流研究、镓-67扫描）、超声、CT及血管造影检查结果术前诊断为肝癌，但我们病例中的肝脏肿块最终证实为肝放线菌病。由于肝放线菌病罕见，在肝脏肿块病变的鉴别诊断中常被忽视。它应纳入肝脏高血运肿块病变的范畴。
