Objective:To investigate CT manifestations of inflammatory pseudotumor of the spleen and their diagnostic value. Methods:The clinical and CT data of 8 cases confirmed by surgery and pathology of inflammatory pseudotumor of the spleen were retrospectively analyzed and reviewed the CT appearances in combination with the literatures relevant to this disorder. Results: A total of 9 foci of 8 patients were showed low density in CT scan. Of these 9 fouci. 7 presented with clear edge and 2 with slightly indistinct borders, in which the density of the bigger foci were uneven. 2 foci were not enhanced obviously and 7 were a little enhanced during the arterial phase. While. 8 foci were strengthened and the smaller foci were isodense in the portal venous phase. Conclusion:The dynamic enhanced CT on inflammatory pseudotumor of the spleen exhibits the characteristics in terms of continuity, progressive enhancement, and delayed enhancement, which is of great value in the diagnosis and differential diagnosis of inflammatory pseudotumor of the spleen.%目的:探讨脾脏炎性假瘤的CT表现及其诊断价值.方法:回顾性分析8例经手术和病理证实的脾脏炎性假瘤的临床和CT资料,并结合文献探讨其CT表现.结果:8例患者共9个病灶中CT平扫均表现为低密度灶,其中7个病灶边界清楚,2个病灶边缘稍模糊,较大的病灶其内密度不均匀；增强扫描动脉期2个病灶无明显强化,7个病灶仅有轻度强化,门脉期及延迟扫描8个病灶呈渐进性持续强化,较小的病灶甚至可呈等密度.结论:脾脏炎性假瘤在CT动态增强扫描时具有持续性、渐进性强化和延迟强化的特征性表现,螺旋CT对脾脏炎性假瘤的诊断和鉴别诊断具有重要价值.
