目的 分析纤维瘤和纤维肉瘤的CT表现 ,为临床的诊治提供依据。方法 对经手术病理证实的硬纤维瘤 6例 (鼻腔 3例、上颌窦 2例、软腭 1例 )和纤维肉瘤 2例 (上颌窦及鼻腔各 1例 )进行回顾性分析 ,CT采用轴位扫描 ,层厚和间隔均为 5mm。结果 纤维瘤CT表现为单发圆、半圆或椭圆形实性软组织肿块 ,密度多均匀 ,边缘清楚、整齐 ,有包膜 ,带蒂或有广基 ,造影后轻 -中度强化 ;肿瘤呈膨胀性生长 ,周围骨质受压变薄或吸收 ,邻近结构受推移。纤维肉瘤则表现为此部位恶性肿瘤共同的CT征象。结论 纤维瘤的CT表现有一些特点 ,可与该部位大多数常见良性病变相鉴别。纤维肉瘤则无法与其他恶性肿瘤相区别 ,二者诊断均需依靠病理
Objective To analyze the CT findings of fibroma and fibrosarcoma and provide the basis for clinical diagnosis and treatment. Methods Six cases of pathologically confirmed hard fibroma (3 cases of nasal cavity, 2 cases of maxillary sinus, 1 case of soft palate) and 2 cases of fibrosarcoma (1 case of maxillary sinus and nasal cavity) were retrospectively analyzed. CT was performed with axial scanning , Layer thickness and spacing are 5mm. Results CT showed single solidified round, semicircular or oval solid soft tissue mass with more uniform density, clear margin, neat edges, enveloped, pedunculated or broad base, mild to moderate contrast enhancement Sexual growth, the surrounding bone thinning or absorption, the adjacent structure by the shift. Fibrosarcoma is manifested as common CT signs of malignancy in this area. Conclusion The CT findings of fibroids have some characteristics that can be differentiated from the most common benign lesions in this area. Fibrosarcoma can not be distinguished from other malignancies, the diagnosis of both need to rely on the pathology
