肝细胞腺瘤为十分罕见的肝脏良性肿瘤,1973年Baum首先报道口服避孕药与肝细胞腺瘤有关。指出,避孕药与其同类药物,可引起肝细胞腺瘤。过去多在手术后或尸检中发现,术前不易确诊。近几年来,随着影像技术的发展,术前诊断已成为可能。本文通过回顾分析4例肝细胞腺瘤的声像图表现及CT、MRI的主要特征,并与病理对照,旨在提高对本病的认识。 Hepatocellular adenoma is a very rare liver benign tumor. Baum first reported in 1973 that oral contraceptives were associated with hepatocellular adenoma. Pointed out that contraceptives and their similar drugs, can cause hepatocellular adenoma. In the past mostly after the operation or autopsy found that preoperative diagnosis is not easy. In recent years, with the development of imaging technology, preoperative diagnosis has become possible. In this paper, through retrospective analysis of four cases of hepatocellular adenoma sonography and CT, MRI of the main features, and pathological control, aimed at raising awareness of the disease.
