摘　　要：壶腹周围癌是对生长在乏特壶腹、十二指肠乳头、胆总管下端及十二指肠内侧壁癌的总称,为一种少见的消化系统恶性肿瘤[1].本研究回顾性分析2007年1月至2012年7月我院收治的12例壶腹周围癌患者的临床资料,对比超声造影、MRI平扫+MRCP检查结果,旨在总结壶腹周围癌的影像学特征,探讨不同影像学检查对壶腹周围癌的诊断价值.Periampullary carcinoma is a rare malignant tumor of digestive system, and its accurate diagnosis is still difficult. From January 2007 to July 2012,12 patients with periampullary carcinoma had been admitted to the Southwest Hospital of Third Military Medical University, and the imaging data were retrospectively analyzed. The results of ultrasonography revealed that all tumors were hypoechoic. The tumor displayed hyperenhancement in 3 patients, isoenhancement in 1 patient, hypoenhancement in 8 patients during the arterial phase on contrastenhanced uhrasonography （ CEUS）, while the tumor displayed hypoenhancement in all patients during the venous phase. Magnetic resonance imaging （MRI） plain scanning showed duodenal papilla enlargement in 1 patient, ampullary tissue mass signal in 2 patients, tissue mass signal at distal common bile duct in 2 patients, the rest 7 patients did not show tissue mass signal. Lower biliary obstruction was the common manifestation of the 12 patients on magnetic resonance cholangiopancreatography （ MRCP）, intrahepatic and extrahepatic bile vine-like expansion in 4 patients, ＂double duct sign＂ in 2 patients, the bottom of common bile duct with filling defect in 2 patients and it revealed beak-like narrow in 1 patient. CEUS, MRI and MRCP could both play an important role as conventional methods in diagnosing periampullary carcinoma.
