摘要
目的:探讨霉菌性鼻窦炎的特征性CT和MRI表现。方法:回顾性分析经手术病理证实的28例霉菌性鼻窦炎的临床及CT、MRI资料。结果:病变累及一侧上颌窦者17例,累及一侧上颌窦及同侧筛窦者5例,累及一侧上颌窦及同侧筛窦、鼻腔者3例,累及双侧上颌窦者3例。病理表现为被覆假复层纤毛柱状上皮黏膜组织中有较多炎性渗出物、坏死物及淋巴细胞和多形核细胞浸润,可见菌丝、孢子。霉菌性鼻窦炎的CT表现主要为病变窦腔软组织影充填20例,病灶内斑点、条片样钙化26例,窦腔骨壁增厚21例,窦腔缩小15例,偶见骨壁破坏4例;MRI表现主要为病变T1WI呈等信号或低信号,T2WI呈低信号或混合不均匀信号,周围见T1WI低信号、T2WI高信号影充填窦腔或窦壁黏膜增厚。结论:CT是诊断霉菌性鼻窦炎的首选影像学检查方法,MRI能显示病灶内真菌球范围,有助于鉴别诊断。
Objective:To evaluate the CT and MRI characteristics of fungal paranasal sinusitis.Methods:The clinical and imaging materials of 28 patients with surgery and pathology proved fungal paranasal sinusitis were analyzed retrospectively.Results:Of the 28 patients,17 patients had involvement of unilateral maxillary sinus,5 patients had unilateral maxillary sinus and ipsilateral ethmoid sinus involvement,3 patients had unilateral maxillary sinus,ipsilateral ethmoid sinus and nasal cavity involvement,3 cases had bi...
