【摘要】 目的:探讨鼻窦鼻腔区域(窦鼻区)中线破坏性疾病的CT表现。方法:回顾16例窦鼻区中线破坏性疾病临床、病理及CT资料。病理诊断:13例淋巴瘤,1例Wegener肉芽肿病,2例恶性肉芽肿。结果:窦鼻区中线破坏性疾病CT表现相似。其表现有:①病灶呈单或双侧鼻腔分布;②筛窦和上颌窦经常受侵;③部分病灶累及鼻翼和上颌窦前脂肪垫;④累及鼻咽部可表现后鼻孔肿块或咽壁增厚;⑤少数可侵犯颅内、腭、眼眶、翼腭窝、颞下窝、翼颌间隙等;⑥无骨质破坏或局部轻度破坏,有时骨质破坏与增生并存。结论:窦鼻区中线破坏性疾病,特别是早期局限的病变,CT表现几乎缺乏特异性,鉴别诊断上应将淋巴瘤和Wegener肉芽肿病考虑在内。确诊有赖于病理检查。更多还原

【Abstract】 Objective:To probe the computed tomographic findings of the midline destructive lesions of the sinonasal tract.Methods:We reviewed the CT studies and clinical,pathologic data of 16patients with midline destructive diseases of the sinonasal tract.Results:No differences could be found in the CT findings of these diseases.Their CT features included:①unilateral or bilateral distribution of the lesions.②the ethmoid and maxillary antrums were involved more frequently.③in-vasion of the nasal alae and fat pad in front of the maxillary antrum occurred occasionally.④nasopharyngeal involvements pre-sented as a choanal mass or infiltration of the nasopharyngeal walls.⑤intracranial and orbital involvements occurred occasionally and at times pterygopalatine fossa,infratemporal fossa,pterygomaxillary space were aggressed.⑥without or just a little bone erosion,while sometimes erosion as well as proliferation can be found.Con clusion:The midline destructive lesions frequently have the same clinical and imaging features,differential diagnosis of nasal lymphoma and Wegener’s granulomatosis should be considered.The final decision depends on pathological examination.更多还原
