摘要

肝內膽管囊腺瘤(biliary cystadenoma)是一種很罕見的腫瘤，而單純性肝囊泡(simple hepatic cysts)，卻是常常可見的。如果沒有看到內部分隔或是結節的話，我們很容易會把肝內囊狀腫瘤誤認為單純性肝囊泡。在此我們報導一位有多發性單純肝囊泡的七十歲女性，其中的一顆最後診斷為肝內膽管囊腺瘤。因為這顆囊狀腫瘤在超音波下很像單純性肝囊泡，所以一年後才被電腦斷層診斷出來。電腦斷層可以進一步看到很薄的內部分隔和局部不規則的邊緣進而做出正確診斷。

Intrahepatic biliary cystadenoma is a rare disease with only a few reports in the literature. On the other hand, simple hepatic cysts are frequently encountered in daily practice. Unless finding internal septa or mural nodules, we regard the welldefined intrahepatic cystic lesions with homogenous content as simple hepatic cysts. Here we report a 70-year-old woman with multiple, simple hepatic cysts, one of which was biliary cystadenoma. Ultrasound (US) failed to detect the simple cyst mimicker amongst the hepatic simple cysts for one year. Finally abdominal multidetector computed tomography (MDCT) detected the subtle thin internal septa and focal irregular wall, a key feature for the diagnosis of biliary cystadenoma.
