目的　探討鐮狀韌帶引起假性病灶的影像學表現，以提高對其的認識，減少誤診。方法　對2010年1月－2012年1月收入的817例患者進行上腹部64排CT平掃加增強掃描，篩選出肝鐮狀韌帶附近假病灶，詳細記錄其部位、大小、形狀以及掃描各期圖像的密度變化情況。結果　有72例存在鐮狀韌帶假病灶，絕大多數位于肝左葉內側段（69例），并呈單發病灶（70例）。假病灶最大直徑約5.1～22.0 mm，平均約13.1 mm，假病灶分別呈三角形43例、類圓形19例、結節狀10例。CT掃描：平掃顯示10例，動脈期顯示63例，門脈期幾乎全部顯示清晰。結論　鐮狀韌帶形成假病灶比較少見，其發生部位特殊，在門脈期易于顯示，可與肝內真性病灶鑒別，以免誤診。
