OBJECTIVE
This study was conducted to describe the MR imaging features of solid pseudopapillary tumor of the pancreas.
CONCLUSION
Solid pseudopapillary tumor of the pancreas, a tumor typically seen in young women, is a large, well-defined, encapsulated lesion with heterogeneous high or low signal intensity on T1-weighted, heterogeneous high signal intensity on T2-weighted, and early peripheral heterogeneous enhancement with progressive fill-in on gadolinium-enhanced dynamic MR imaging. These features help differentiate this rare tumor from other pancreatic neoplasms.
目的
本研究旨在描述胰腺实性假乳头状瘤的磁共振成像（MR）特征。
结论
胰腺实性假乳头状瘤是一种多见于年轻女性的肿瘤，为边界清晰、有包膜的大肿块，在T1加权像上呈不均匀高信号或低信号，T2加权像上呈不均匀高信号，钆增强动态MR成像表现为早期周边不均匀强化并逐渐填充。这些特征有助于将这种罕见肿瘤与其他胰腺肿瘤区分开来。
