目的 :探讨鼻腔、副鼻窦几种良性肿瘤的CT诊断和鉴别。方法 :对经手术和病理证实的 49例 (纤维瘤 5例 ,神经纤维瘤 6例 ,纤维血管瘤 2 0例 ,骨化纤维瘤 6例及内翻乳头状瘤 12例 )病人的临床、病理及CT表现进行分析对照。CT扫描采用轴位、层厚及层距 5mm ,部分病例用静脉团注增强后扫描 ,测量增强前后肿瘤的平均CT值。结果 :各种肿瘤各自不同的病理改变决定了不同的CT特征 ,它们在好发部位、病变大小、形态、钙化、增强等方面均有不同。结论 :根据CT表现可提示诊断 ,但需要与该部位的其它良性肿瘤及一些早期恶性肿瘤相鉴别。
Objective: To investigate CT diagnosis and differential diagnosis of several benign tumors of nasal and paranasal sinuses. Methods: The clinical and pathological features of 49 cases (5 cases of fibroma, 6 cases of neurofibroma, 20 cases of hemangiomas, 6 cases of ossification fibroses and 12 cases of inverted papillomas) confirmed by operation and pathology And CT performance analysis and control. CT scan axial position, layer thickness and layer spacing 5mm, in some cases with intravenous bolus enhanced scan after the enhancement measured before and after the average tumor CT value. Results: The different pathological changes of various tumors determine different CT features. They have different appearances, lesion size, morphology, calcification, enhancement and so on. Conclusion: According to CT findings can be prompted to diagnose, but with the site of other benign tumors and some early malignant tumor phase identification.
