摘要
目的探讨霉菌性副鼻窦炎的CT特征。方法回顾分析20例经手术病理证实的霉菌性副鼻窦炎的CT表现。结果单侧副鼻窦发病18例,双侧副鼻窦发病2例,全部病变均累及上颌窦,累及2个以上副鼻窦腔8例,病变侵犯后鼻孔2例。霉菌性副鼻窦炎的CT表现主要为病变窦腔内充满软组织影,密度增高,不均匀,病灶内出现点状、条状钙化灶,窦腔骨壁增厚伴破坏,窦腔缩小。结论霉菌性副鼻窦炎的CT表现具有单侧发病为主,窦腔内点状、条状钙化灶,窦腔骨壁增厚伴破坏以及窦腔缩小等特征。CT可为诊断本病提供重要信息,但确诊需要组织学和细菌学检查。
Objective To study the CT findings of mycotic paranasal sinusitis.Methods CT findings of 20 patients with surgically and pathologically proved mycotic paranasal sinusitis were analyzed retrospectively.Results Among 20 patients with mycotic paranasal sinusitis,unilateral and bilateral lesions were found in 18 and 2 cases,respectively.All the lesions were involved into the maxillary sinuses.The involvement of 2 or more than 2 paranasal sinuses and the invasion of posterior nares were found in 8 and 2 cases,respectively.The main CT signs of mycotic paranasal sinusitis appeared as the affected sinus cavities to be filled by the soft tissue shadows with hyperdense or heterogeneous density,intralesional punctate or stripe calcification,and the shrunk of the sinus cavities.Conclusion CT findings of mycotic paranasal sinusitis are mainly characterized by unilateral lesions,intraluminal punctate or stripe calcified foci,thickening of the sinus walls associated with bone destruction,and shrunk of the sinus cavities.CT can provide important information to diagnose this disease but the definitive diagnosis requires histologic and bacteriologic examinations.
