摘要本文报告一位接受第八肝段部分切除术之胆管腺瘤之电脑断层摄影（CT）及磁振造影（MR）表现。CT上BDA显示环形高密度区，提示钙化和环形强化。在T1和T2加权MR图像上均呈低信号。术前考虑的诊断包括转移癌、胆管癌、结核和罕见肿瘤如上皮样血管内皮瘤。影像学表现经病理证实。
Computed tomographic (CT) and magnetic resonance (MR) appearances of bile duct adenoma (BDA in a patient who underwent partial hepatectomy of segment 8 are presented. BDA showed a ring-shaped hyperdense area suggesting calcification and ring enhancement on CT. It appeared hypointense on both T1- and T2-weighted MR images. Preoperatively, the diagnoses considered included metastatic carcinoma, cholangiocarcinoma, tuberculosis, and rare tumors such as epithelioid hemangioendothelioma. The radiological findings were confirmed by pathological investigation.
