To evaluate the radiologic characteristics of intraductal mucin-producing tumors of the pancreas.
Sixteen patients with intraductal tumors underwent ultrasound (US); (n = 15), computed tomography (CT); (n = 16), endoscopic retrograde cholangiopancreatography (ERCP); (n = 12), and intraoperative pancreatography (n = 2). Findings were compared with those from surgery (n = 14) or biopsy (n = 2).
Lesions were classified as either main duct type or branch duct type tumors. Main duct tumors were characterized at US and CT by either diffuse or segmental dilatation of the Wirsung duct. Pancreatography showed ductal dilatation and filling defects caused by mucin deposits. At US and CT, branch duct tumors, which were mainly located at the uncinate process, were seen as fluid-filled masses with central septa and the pancreatic duct was dilated. ERCP showed partial or complete opacification of the lesion. In four patients, endoscopy showed protrusion of the papilla into the duodenal lumen and mucin leaking from its dilated orifice.
Imaging modalities, especially US and ERCP, enable early diagnosis of mucin-producing pancreatic tumors.
评估胰腺导管内黏液性肿瘤的放射学特征。
16例导管内肿瘤患者接受了超声检查（US）（n = 15）、计算机断层扫描（CT）（n = 16）、内镜逆行胰胆管造影（ERCP）（n = 12）以及术中胰管造影（n = 2）。将检查结果与手术（n = 14）或活检（n = 2）结果进行比较。
病变分为主胰管型或分支胰管型肿瘤。主胰管肿瘤在超声和CT上的特征为Wirsung管弥漫性或节段性扩张。胰管造影显示导管扩张及黏液沉积所致的充盈缺损。在超声和CT上，主要位于钩突的分支胰管肿瘤表现为有中央分隔的液性肿块，且胰管扩张。ERCP显示病变部分或完全显影。4例患者的内镜检查显示乳头突入十二指肠腔，黏液从其扩张的开口处漏出。
影像学检查方法，尤其是超声和ERCP，能够实现对胰腺黏液性肿瘤的早期诊断。
