真菌球型鼻窦炎的CT诊断价值

The CT diagnostic value of fungus ball rhinosinusitis

目的:探讨真菌球型鼻窦炎CT影像特征和诊断价值。方法:回顾2016年4月—2018年5月我院16例真菌球型鼻窦炎患者CT影像表现,分析总结病变的部位、软组织密度、钙化形态及位置、窦壁骨质改变等CT影像特征。结果:16例中单发13例,多发3例,单侧上颌窦12例,累及单侧上颌窦及筛窦2例,单侧蝶窦1例,双侧上颌窦1例。16例病变窦腔内见较高软密度组织影,病变密度不均匀,13例不均匀软组织肿块内见斑点状、条状或结节状高密度钙化影,7例有窦壁增生、硬化,4例窦腔缩小。结论:真菌球型鼻窦炎的CT影像特征为单侧、单鼻窦发病为主,窦腔不均匀稍高密度软组织影内斑点状、条状或结节状钙化灶具有较高诊断价值。

Objective To investigate the CT diagnostic value and CT features of fungal ball rhinosinusitis. Methods From April 2016 to May 2018,we retrospectively reviewed the CT imaging findings of 16 cases of fungus ball rhinosinusitis in our hospital, and analyzed the CT characteristics of lesions such as lesion location, soft tissue density, calcification morphology and location, and adjacent bone changes. Results Among the 16 cases, there were 13 cases of unilateral sinusitis, 3 cases of double sinusitis, 12 cases of unilateral maxillary sinus, and 2 cases involved unilateral sinus and ethmoid sinus, 1 case was unilateral sphenoid sinus, and 1 case was bilateral maxillary sinus.In the 16 cases, the lesions showed higher soft tissues shadow and heterogeneous lesion density in sinus cavity. 13 cases showed punctate, stripeor nodularhigh-densitycalcifications in soft tissues mass, 7 cases showed sinusoidal hyperplasia, sclerosis,and 4 cases showed sinus cavities shrink.Conclusion The CT image features of fungal ball rhinosinusitis is that it mainly mainly occurred in unilateral and single sinus.The punctate, stripe or nodularcalcifications in heterogeneous and slightly high-densitysoft tissue in sinus cavity has high diagnose value.
