To document the clinical and imaging characteristics of fungal rhinosinusitis (FRS).
Imaging studies of 28 patients with FRS were retrospectively analyzed, considering the type of fungal disease, location, signal characteristics, bone changes, expansion, and extrasinus extension.
Acute invasive FRS showed unilateral pacifications of the sinonasal cavity, perisinus fat infiltration and/or bone destruction. Chronic invasive FRS demonstrated masslike hyperattenuating soft tissue, with bony destruction. The soft tissue changes were hypointense on T1 and markedly hypointense on T2-weighted images. In allergic FRS, hyperattenuating soft tissue causing paranasal expansion due to allergic mucin was observed on CT. Fungus ball presented as a hyperattenuating lesion with calcifications within a single sinus.
The radiological features of each type of FRS are distinctive and should afford a specific diagnosis in the proper clinical setting.
记录真菌性鼻窦炎（FRS）的临床和影像学特征。
回顾性分析28例FRS患者的影像学研究，考虑真菌疾病类型、位置、信号特征、骨质改变、扩张及鼻窦外扩展情况。
急性侵袭性FRS表现为鼻窦腔单侧闭塞、鼻窦周围脂肪浸润和/或骨质破坏。慢性侵袭性FRS显示肿块样高密度软组织，伴有骨质破坏。软组织改变在T1加权像上呈低信号，在T2加权像上呈明显低信号。在变应性FRS中，CT上可见因变应性黏液导致鼻窦扩张的高密度软组织。真菌球表现为单个鼻窦内有钙化的高密度病变。
每种类型的FRS的放射学特征都很独特，在适当的临床情况下应能做出明确诊断。
