目的探讨上颌窦炎性假瘤的CT和MRI表现特征。方法回顾性分析6例上颌窦炎性假瘤的影像资料，3例行CT检查，3例行MRI扫描。结果发生于左侧上颌窦2例；右侧上颌窦4例。CT扫描：窦腔充满等密度软组织肿块；窦壁骨质弥漫硬化、增厚，伴发虫蚀样骨质吸收、破坏，1例眼眶受侵、1例翼腭窝受侵。MRI扫描：与脑实质比较，窦腔肿块T1WI呈等信号，T2WI呈不均匀低信号。结论 CT窦壁增厚、硬化伴发虫蚀样骨质吸收、破坏和病变 T2WI不均低信号为该病特征性表现，CT和MRI两种影像检查方法联合应用能够对该病的诊断和治疗提供更全面的信息。

Objective To analyze the CT and MR findings in 6 cases of inflammatory pseudotumor of the maxil ary sinus. Methods Imaging data of 6 patients with inflammatory pseudotumor of the maxil ary sinus were analyzed,including CT images were 3 cases and MRI findings were 3 cases. Results Among 6 cases, the lesion located in left maxil ary sinus in 2 cases and right maxil ary sinus in 4 cases. On precontrast CT, 6 maxil ary sinuses in al 6 cases were fil ed in isointense density soft-tissue mass. The lesion resulted in thickening,sclerosing with absorption and destruction of the bone wal . The lesion involved orbit in 1 case. The lesion involved fossa pterygopalatina in 1 case. On precontrast MRI T1WI,the lesion demonstrated isointense signal intensity compared to brain in al 6 cases. On precontrast MRI T2WI,the lesion showed heterogeneous low signal intensity in al 6 cases. Conclusion Bone wal thickening,sclerosing with absorption and destruction on CT and lesion heterogeneous low signal intensity MRI T2WI were typical manifestations of inflammatory pseudotumor of the maxil ary sinus.Combined findings of CT and MRI can provide more comprehensive information for the diagnosis and therapy.
