目的探讨腭部肿瘤多层螺旋CT(multi-slice spiral CT,MSCT)的诊断价值。方法回顾性分析18例经病理证实的腭部肿瘤的CT表现,包括病灶的部位、大小、形态、边缘、密度及强化特点等,其中良性肿瘤7例,恶性肿瘤11例,均行MPR技术作冠状面、矢状面重组,多方位、多窗位观察分析病变。结果 7例腭部良性肿瘤表现为卵圆形或类圆形软组织肿块,密度均匀、轻中度均匀强化,边界清楚,3例伴有邻近骨质压迫吸收;11例腭部恶性肿瘤表现为不规则软组织肿块、不均匀强化,边界不清,6例伴有邻近骨质不规则破坏、邻近结构受侵,5例伴有颈淋巴结转移。结论多层螺旋CT能立体显示病变,对腭部肿瘤作出准确定位诊断、对良恶性肿瘤的鉴别诊断以及恶性肿瘤侵犯范围的判定都具有重要意义。
Objective To investigate the diagnostic value of multi-slice spiral CT (MSCT) in palatal tumors. Methods Retrospective analysis of 18 cases of pathologically confirmed palatal tumors CT features, including the location of lesions, size, shape, edge, density and enhanced features, including 7 cases of benign tumors, 11 cases of malignant tumors were performed MPR Coronal, sagittal reorganization, multi-directional, multi-window observation and analysis of lesions. Results Seven cases of palatal benign tumors showed oval or oval soft tissue mass with uniform density, mild to moderate homogeneity, clear boundary and three cases with adjacent bone compressions. Eleven palatal malignant tumors showed no Regular soft tissue mass, uneven enhancement, the border is unclear, 6 cases with adjacent bone irregular destruction, adjacent structures invaded, 5 cases accompanied by cervical lymph node metastasis. Conclusion Multi-slice spiral CT can display the lesions stereotacticly, diagnose the palate tumors correctly, and have a great significance in the differential diagnosis of benign and malignant tumors and the determination of the extent of malignant tumor invasion.
