目的探讨胰腺实性假乳头状瘤(solid-psuedopapilary tumor of pancrea,SPTP)的CT表现与病理学特征,提高诊断正确率。方法对5例经病理证实的SPTP患者的CT表现及病理资料进行对照研究。结果 5例SPTP患者中,男1例,女4例。CT平扫表现为胰腺区囊实性肿块,包膜大多完整,增强扫描示动脉期实性部分轻度强化,门静脉期及延迟期强化程度逐渐增加,与胰腺分界清。组织学上,以瘤细胞围绕血管排列成假乳头状结构且伴有退行性改变为其特征。结论胰腺实性假乳头状瘤的CT表现有一定特点,病理变化是CT表现的基础。
Objective To investigate the CT features and pathological features of solid-psuedopapillary tumor of pancrea (SPTP) and to improve the diagnostic accuracy. Methods CT findings and pathological data of 5 patients with pathologically confirmed SPTP were compared. Results In 5 cases of SPTP patients, 1 males and 4 females. CT scan showed pancreas cystic mass, most of the intact capsule, enhanced scan showing the solid part of the arterial phase mild enhancement, portal phase and delayed phase enhancement gradually increased, and the clear division of the pancreas. Histologically, tumor cells are arranged around the blood vessels into pseudopapillary structures with degenerative changes. Conclusion The CT findings of solid pseudopapillary tumors of the pancreas have certain characteristics. The pathological changes are the basis of CT findings.
