真菌性鼻窦炎的MRI诊断

MRI diagnosis of fungal sinusitis

目的:探讨真菌性鼻窦炎的MRI表现特征,分析诊断价值。方法:回顾分析11例经手术病理证实为真菌性鼻窦炎患者的MRI资料及临床表现。结果:9例累及上颌窦,其中3例累及同侧筛窦,1例累及双侧上颌窦、筛窦、额窦,1例累及蝶窦。病变信号混杂,T1WI呈低、等及长信号,T2WI呈高低混合信号,霉菌球呈短T1、短T2信号。结论:真菌性鼻窦炎具有较特征性的MRI表现,在诊断和鉴别诊断中具有较高价值。

Objective： To study the fungal sinusitis features in MRI.Methods： MRI materials and clinical manifestations of eleven patients with fungal sinusitis confirmed by operation and pathology were analysed.Results： Nine cases involving the maxillary sinus,3 cases involving the same side ethmoidal sinus,1 case involving the bilateral maxillary sinus,ethmoidal sinus,and frontal sinus,1 case involving the sphenoid sinus.Lesions signals were mixed,T1WI was low and long signal,T2WI was high and low mixed signal,mold ball presented T1,T2 short signal.Conclusion： Fungal sinusitis has accurate information used MRI in the diagnosis and differential diagnosis of high value.
