真菌性鼻窦炎的CT表现及其诊断价值研究

目的通过研究CT检查在真菌性鼻窦炎病变中的影像学特征,分析其诊断价值,以提高真菌性鼻窦炎的术前确诊率。方法回顾性分析20例真菌性鼻窦炎患者的CT表现特点。结果单侧发病17例,双侧发病3例;上颌窦发病20例,累及同侧筛窦4例;多数窦腔病灶部位可见高密度不均匀的钙化影,多为斑点状、棉絮状、条状等,可伴有局限性骨质吸收破坏、增生硬化、窦口扩大等表现。结论窦腔软组织内散在的不均匀高密度钙化影是真菌性鼻窦炎患者主要的CT征象;多表现为单侧发病,上颌窦最易受累;CT检查对于真菌性鼻窦炎患者的诊断、病变范围以及受累程度的判断具有重要的参考价值。

The Characteristic Manifestation and Diagnostic Value of Fungal Sinusitis on CT

Objective To investigate the characteristic manifestation of fungal sinusitis on CT and assess its value in the clinical diagnosis and to improve its radiological diagnosis. Methods The CT manifestation was analyzed retrospectively with data from 20 patients in our department between 2009 and 2013. Results 17 cases with unilateral disease, 3 patients with bilateral disease, 20 cases with maxillary sinus disease, 4 cases of them were affected by the ipsilateral ethmoidal anfractuosity. Most sinus lesions showed high density inhomogeneous calcification, punctate,plaquelike and linear calcified image were found, can be accompanied by localized bone absorption destruction, sclerosis, ostium enlargement. Conclusions The most vulnerable is the maxillary sinus, focus of infection is most unilateral. Most of fungus sinusitis which can be showed on CT scan are inhomogeneous calcification in sinus cavity parenchyma. CT is extremely important for diagnosis of fungal sinusitis and the extent of the lesion involvement and degree of judgment.
