真菌性鼻窦炎的CT与临床诊断

目的：探讨真菌性鼻窦炎的CT和临床特征以及新的分类。资料与方法：回顾性分析经手术、病理证实的34例真菌性鼻窦炎患者的CT表现。结果：CT征象：（1）所有受累鼻窦均显示窦腔内密度增高影；（2）上颌窦内可见团块状或线样钙化影25例（73．5％）；（3）窦腔高密度湿浊影中有气泡影8例；（4）上颌窦骨质吸收、破坏5例，窦壁骨质膨胀或变薄3例。结论：真菌性鼻窦炎有特征性的CT表现，如窦腔内可见团块状高密度影、线样钙化影或气泡影等。CT扫描结合鼻内镜检查是诊断本病的重要手段。

CT and Clinical Diagnosis of Fungal Paranasal Sinusitis

Objective To study the clinical and CT features of fungal paranasal sinusitis, and to try to make a new classification of the disease. Materials and Methods CT findings in 34 patients with pathologically-proved fungal paranasal sinusitis were retrospectively analyzed. Results The following CT signs were observed. (1) Increased attenuation of diseased paranasal sinuses (n=34). (2) Lump or linear calcification in maxillary sinus (n=25, 73.5%). (3) Air bubbles within high-dense muddy shadow in maxillary cavity (n=8). (4) Bony destruction or absorption (n=5), expanding or thinning (n=3) of maxillary sinus wall.Conclusion Fungal paranasal sinusitis carries some characteristics on CT scan, such as lump high-dense shadow, linear calcification and air bubbles within the diseased sinus. Combined with nasal endoscopy, CT scanning can provide important diagnostic information.
