目的探讨螺旋CT扫描在非侵袭性真菌性上颌窦炎诊断中应用价值。方法对31例真菌性上颌窦炎的螺旋CT扫描结果及鼻内镜术中表现、术后病理检查结果等资料进行回顾性分析。结果 12例患者单侧上颌窦腔内不均匀的密度增高影,影像诊断考虑为上颌窦真菌球(FB);16例患者双侧上颌窦、筛窦内软组织密度影充填(以单侧上颌窦为主),影像诊断考虑为变应性真菌性上颌窦炎(AFRS);3例患者鼻窦CT未见明显的钙化点、斑及骨质吸收破坏,术前考虑为慢性鼻窦炎(双侧),31例均经鼻内镜术中所见及术后病理证实为真菌病。结论 CT扫描在非侵袭性真菌性上颌窦炎的诊断中具有十分重要的诊断价值。
Objective To investigate the value of spiral CT in the diagnosis of noninvasive fungal maxillary sinusitis. Methods The results of spiral CT scan of 31 cases of fungal maxillary sinusitis and the results of endoscopic sinus surgery and postoperative pathological examination were retrospectively analyzed. Results The density of unilateral maxillary sinus cavity was increased in 12 patients. The diagnosis of maxillary sinus was considered as fungal ball (FB). Sixteen patients underwent maxillofacial and ethmoid sinus soft tissue density imaging (unilateral maxillary sinus (AFRS). No significant calcification, plaque and bone resorption were found in 3 cases of CT, and preoperative consideration was chronic sinusitis (bilateral) , 31 cases were confirmed by endoscopic sinus surgery and postoperative pathology as fungal disease. Conclusion CT scan has very important diagnostic value in the diagnosis of non-invasive fungal maxillary sinusitis.
