摘要: 目的 分析胰腺实性假乳头状瘤的CT表现,提高正确诊断率。方法 回顾分析经手术病理证实的21例胰腺实性假乳头状瘤,患者术前均经CT平扫及三期增强检查,复习CT影像表现并与病理对照。结果 21例胰腺实性假乳头状瘤中13例位于胰头,8例位于体尾部,肿瘤直径2~15cm。19例与周围组织界限清,具有完整的包膜,以囊实性为主,囊最大直径4cm,囊壁厚0.2~3cm;仅2例为实性。位于胰头的肿瘤胰管及胆总管扩张不明显。CT平扫示肿瘤密度不均匀;CT增强扫描示动脉期实性部分轻度强化,门脉期及延迟期强化程度逐渐增加。结论CT对此胰腺肿瘤的诊断具有一定的价值,病理变化是CT表现基础。

Abstract: Objective: To analyze the CT appearance of solid-pseudopapillary tumor of pancreas (SPTP) and enhance the accurate diagnostic rate Methods: 21 patients with surgically and pathologically confirmed SPTP were reviewed. All cases underwent unenhanced spiral scanning CT and three phases post-contrast scanning. The CT imaging were analyzed in comparison with surgical pathological features. Results: Thirteen cases were located in pancreatic head, 8 located in pancreatic body and tail .The diameter of tumors were 2~15cm, 19 were well-circumscribed and encapsulated, most tumor including cystic and solid portion , the largest diameter of cyst was 4cm, the wall thickness were 0.2~3cm, only 2 were completely solid; The pancreatic head tumors did not cause pancreatic duct and common bile duct dilate obviously. The unenhanced CT scanning showed that tumors were non-homogeneous .On post-contrast CT, the solid portion were slightly enhanced in the arterial phase and markedly enhanced in portal and delay phase. Conclusions: CT was helpful in diagnosing SPTP,the appearance of CT was based on pathology.
