| 目的 探讨胰腺囊性肿瘤的影像学特征。方法 对19例胰腺囊性肿瘤的B超、CT、钡餐造影检查(GI) 和逆行胰胆管造影(ERCP)资料进行回顾性分析。结果 B超:4例囊腺瘤中2例囊性,2例为不均匀的低回声光团。12例囊腺癌均为囊性,部分病例见条索状分隔或乳头状突起。CT:5例囊腺瘤中3例囊性,2例为不均匀低密度肿物;10例囊腺癌皆为囊性,部分病例见囊壁薄厚不均、乳头状突起、囊内分隔及周围浸润征象。GI:胃肠道受压移位。ERCP 见胰管受压移位。结论 B超和CT是诊断胰腺囊性肿瘤的有效方法,二者结合使用可提高诊断率。GI和ERCP在鉴别诊断上有一定价值。 |

| Objective To probe into the image characters of pancreatic cystic tumors. Methods Retrospective analysis were made on the image data of B-ultrasound, CT scan, gastrointestinal barium meal examination (GI) and endoscopic retrograde cholangiopancreatography (ERCP) of 19 patients with cystic tumors of pancreas. Results B-ultrasound: out of 4 cases in cystadenoma, 2 appeared cystic while the other 2 were asymmetric low-echo shadow. All the 12 cystadenocarcinoma cases were cystic. Striate septum or papilla were found in some cases. CT scan: in 5 cystadenoma cases, 3 appeared cystic, 2 were asymmetric low-density mass; all the 10 cystadenocarcinoma cases were cystic. Symptoms as cyst wall of uneven thickness, papilla, separation inside cysts, and infiltration in the surroundings were found in some cases. GI: gastrointestinal tract was displaced by tumor press. ERCP: pancreatic tract was displaced by tumor press. Conclusion B-ultrasound and CT scan are effective in the diagnosis of pancreatic cystic tumors, and a combined use of them can increase the precise rate of diagnosis. GI and ERCP are valuable in the differential diagnosis. |
