OBJECTIVE
Our goal was to elucidate the CT and MRI findings of inflammatory pseudotumors of the spleen.
METHODS
The CT and MRI findings of three patients with inflammatory pseudotumors of the spleen were reviewed and compared with the pathologic findings.
RESULTS
On the early phase of CT, the masses were hypodense to the normal spleen, and on the delayed phase, they demonstrated delayed enhancement. On T1-weighted MR images, the masses were isointense to the normal spleen, and on T2-weighted images, the masses had heterogeneous low signal intensities. After administration of Gd-DTPA, the masses showed delayed enhancement.
CONCLUSION
Inflammatory pseudotumors of the spleen were characterized by low signal intensity on T2-weighted MR images and delayed enhancement after contrast material administration on CT and MRI. The fibrous stroma may contribute to these unusual findings.
目的
我们的目标是阐明脾脏炎性假瘤的CT和MRI表现。
方法
回顾了3例脾脏炎性假瘤患者的CT和MRI表现，并与病理结果进行比较。
结果
CT早期，肿块相对于正常脾脏呈低密度，延迟期呈延迟强化。在T1加权磁共振图像上，肿块与正常脾脏信号强度相等，在T2加权图像上，肿块具有不均匀的低信号强度。静脉注射钆喷酸葡胺后，肿块呈延迟强化。
结论
脾脏炎性假瘤的特征是在T2加权磁共振图像上呈低信号强度，在CT和MRI上注射对比剂后呈延迟强化。纤维性基质可能导致这些不寻常表现。
