17例真菌性鼻窦炎的CT诊断分析

CT Diagnosis of fungus infection of paranasal sinuses in 17 cases

目的:探讨真菌性鼻窦炎的CT影像表现特征。方法:回顾性分析17例经组织活检及手术病理证实的真菌性鼻窦炎CT表现。结果:真菌性鼻窦炎多为单侧单窦发病,以上颌窦或以上颌窦为主,可同时累及其他鼻窦。鼻窦内软组织呈结节状或肿块样增生,内可见气泡及点状、条带状钙化。部分窦腔扩大,窦壁骨质增生或破坏。常伴有鼻腔鼻窦结构异常。结论:真菌性鼻窦炎具有特征性的CT表现,CT对该病诊断具有重要价值。

Objective：To evaluate the CT features of fungus infection of paranasal sinuses. Methods：CT findings in 17 cases with fungus infection of paranasal sinuses proved by surgically and biopsy were analyzed. Results： CT findings in fungus infection of paranasal sinuses always unilaterally involved,maxillary sinusis is mainly affected or other paranasal sinuses are involved simultaneously.the soft tissue within the paranasal sinuses presented as nodule-like or tumor-like,and there are some air bubbles and punctuated or banded calcification within the soft tissue.Part of the antrum is enlarged and the bone inside is of hyperosteogeny or destroyed, mostly accompa- riled by abnormal structure of nasal cavity and paranasal sinuses.Conclusion： CT manifestations of fungus infection of paranasal sinuses are of characteristics ,CT scan is of much value in diagnosing this disease.
