目的探讨螺旋CT多期扫描对胰腺实性假乳头状瘤的诊断价值。方法回顾性分析20例经手术病理证实的胰腺实性假乳头状瘤螺旋CT多期扫描图像,比较其在CT平扫及增强扫描各期的强化特点及有无钙化、坏死、囊变等情况。结果 20例胰腺实性假乳头状瘤CT平扫上均表现为边界清晰囊实性包块,大小约2.5～16.5cm,平均5.57cm,增强扫描囊性部分不强化,实性部分动脉期轻度强化,门脉期明显强化,对周围血管无侵犯。结论胰腺实性假乳头状瘤有较特别的增强CT表现,可以在手术前做到定性诊断。
Objective To investigate the value of multi-phase helical CT in the diagnosis of solid pseudopapillary tumor of the pancreas. Methods Retrospective analysis of multi-phase spiral CT images of 20 cases of solid pseudopapillary tumor of the pancreas confirmed by operation and pathology, and comparison of enhancement features and calcification, necrosis, and cystic changes at each phase of CT plain scan and enhanced scan. . Results The plain CT scans of 20 cases of solid pseudopapillary tumor of the pancreas showed clear boundary masses of about 2.5 to 16.5 cm with an average of 5.57 cm. The cystic part of the enhanced scan was not enhanced and the solid part of the arterial phase was light. Intensified, the portal vein was significantly enhanced and there was no invasion of the surrounding blood vessels. Conclusion The solid pseudopapillary tumor of the pancreas has special enhanced CT features and can be diagnosed before surgery.
