孤立性真菌球性蝶窦炎的CT影像学分析

The CT analysis of isolated fungus ball sphenoid sinusitis

目的探讨孤立性真菌球性蝶窦炎的CT影像学特征。方法回顾性分析23例孤立性真菌球性蝶窦炎患者,术前行CT检查和评估,采用经鼻内镜手术治疗,术后通过病理学检查确诊。结果23例患者CT均提示蝶窦腔内浑浊影,其中有高密度的钙化斑块或斑点18例(78.3%),窦腔骨壁增厚5例(21.7%),蝶窦前壁破坏3例(13.1%),窦腔内有气泡样影2例(8.6%),术前影像学诊断结果和术中术腔情况以及术后病理学诊断结果一致。结论CT对孤立性真菌球性蝶窦炎的确诊有独特的临床价值。

Objective To investigate the computed tomography features of isolated fungus ball sphenoid sinusitis. Methods A retrospective study was made in 23 cases of isolated fungus ball sphenoid sinusitis.All the patients underwent CT scanning and evalution preoperatively and then underwent endoscopic surgery, and confirmed diagnosis depends on histopathologic examinantion postoperatively. Results Nasal sinus CT scan showed complete opacification in all 23 cases, with 18 cases （78.3%） had calcification, 5 cases（21.7%） had bones wall thickening, 3 cases （13.1%） had bone erosion of anterior sphenoid sinus, 2 cases （8.6%）had shadow like ＂air bubble＂.The results of CT imaging preoperative diagnosis and intraoperatie diagnosis and postoperative histopathologic diagnosis were consistent. Conclusion Computed tomography has great value for the diagnosis of isolation of isolated fungus ball sphenoid sinusitis.
