Biliary cystadenomas and cystadenocarcinomas are rare cystic neoplasms, usually intrahepatic in location, that are characterized pathologically by a multilocular appearance. We report the CT and sonographic findings in eight cases of biliary cystadenoma and three cases of biliary cystadenocarcinoma and correlate them with the surgical and pathologic findings. CT showed internal septa in eight of the 10 multiloculated lesions, whereas sonography showed septa in all five cases in which it was used. CT in two of the three cystadenocarcinomas showed thick and coarse mural and septal calcifications as well as large solid soft-tissue masses in one. CT showed mural soft-tissue nodules in the single case of a unilocular cystadenocarcinoma. Sonography and CT usually show the multilocular nature of biliary cystadenomas and cystadenocarcinomas. The presence of mural or septal nodules, discrete soft-tissue masses, and possibly thick and coarse calcifications increase the likelihood of a cystadenocarcinoma.
胆管囊腺瘤和囊腺癌是罕见的囊性肿瘤，通常位于肝内，其病理特征为多房性表现。我们报告了8例胆管囊腺瘤和3例胆管囊腺癌的CT和超声检查结果，并将其与手术和病理结果相关联。CT显示10个多房性病变中的8个有内部间隔，而超声检查在其应用的所有5例中均显示有间隔。3例囊腺癌中的2例CT显示壁和间隔有粗大钙化，其中1例还有大的实性软组织肿块。CT在1例单房性囊腺癌中显示壁软组织结节。超声和CT通常显示胆管囊腺瘤和囊腺癌的多房性特征。壁或间隔结节、离散的软组织肿块以及可能的粗大钙化的存在增加了囊腺癌的可能性。
