胰腺实性-假乳头状瘤CT诊断价值简

目的：回顾性分析6例胰腺-实性假乳头状瘤的CT影像学表现特点，探讨CT对该肿瘤的诊断价值。方法收集6例确诊的胰腺实性-假乳头状瘤患者的CT检查资料，对其进行回顾性分析。结果肿块体积均较大，多近似圆形或椭圆形，多有完整的包膜，与胰腺分界清晰，本组病例中，径为4~12 cm，平均7．2 cm，肿瘤位于胰头1例，胰体3例，胰尾2例，以实性成分为主4例，以囊性成分为主2例，边缘光滑，增强扫描肿块动脉期轻度强化，门脉期中度强化，内见囊状无强化区，不伴有胆总管及胰管扩张，多平面重建后，肿块与毗邻组织器官解剖关系显示更加清晰。结论胰腺实性-假乳头状瘤CT影像表现有一定特征，CT检查具有重要的诊断及鉴别诊断意义。

CT diagnostic value of solid-pseudopapillary tumor of pancreas

Objective To study the manifastation of the solid-pseudopapillary tumor of pancreas （SPTP） and to explore its diagnostic value. Methodes CT features of 6 cases comfirmed with SPTP were collected and retrospec-tively analyzed. Results The tumors were usually quite large with the largest diameter ranged from 4 to 12 cm. One case was located in the head of pancreas. Three cases were located in the body of pancreas. Two case were located in the tail of pancreas. Four tumors were mainly composed of solid. Two tumors were mainly composed of cystic parts, which had well-defined margins. Slight enhancement was shown in the arterial phase, and moderately enhanced in the portal venous phase on postcontrast CT scan. The imagings of cystic portions were not enhanced and with lower den-sity. There was no associated dilation of the common bile duct or pancreatic duct. The relationship of the tumor and other organs were displayed clearly by multiplanar reconstruction. Conclusion The CT characteristic findings of SPTP might be of great value for the diagnosis and differential diagnosis.
