【摘要】：目的探讨腭部多形性腺瘤(PA)的CT表现特点。方法回顾性分析23例经病理证实的腭部多形性腺瘤的CT表现并复习相关文献。所有病例均行CT平扫,其中11例行增强扫描。重点对病灶的部位、数目、形态、边缘、密度及强化特征等进行观察分析。结果 23例病变中发生于硬腭9例,软硬腭交界处8例,软腭6例。16例呈类圆形,7例呈椭圆形肿块,界限清楚,平扫时肿块密度等于或稍低于邻近肌肉,14例密度均匀,9例密度不均匀,病灶内可见斑片状或裂隙样低密度区,4例可见钙化或骨化,12例伴有邻近骨质受压吸收,14例病灶周围见环状低密度影。增强后实性部分为轻至中等强化,9例呈不均匀强化,瘤内可见斑片状或裂隙状不强化区,病灶周围环状低密度影不强化,2例强化均匀。结论腭部多形性腺瘤的CT表现具有一定特点,能为术前诊断和治疗提供帮助。
[Abstract]:Objective to investigate the CT features of pleomorphic adenoma of palate (PAA). Methods CT findings of 23 cases of pathologically proved pleomorphic adenoma of palate were analyzed retrospectively and related literatures were reviewed. The location, number, shape, edge, density and enhancement characteristics of the lesions were observed and analyzed in 11 cases. Results among the 23 cases, 9 cases occurred in the hard palate and 8 cases at the junction of the soft hard palate. Soft palate was found in 6 cases. 16 cases were round and 7 cases were oval masses, and the boundary was clear. On plain scan, the density of mass was equal to or slightly lower than that of adjacent muscles in 14 cases, and the density was uneven in 9 cases. In 4 cases, calcification or ossification could be seen in 4 cases with calcification or ossification. Circular low density shadow was seen around the lesion in 14 cases. The solid part of the enhancement was mild to moderate enhancement in 9 cases, and the enhancement was uneven in 9 cases. Patch or fissure unenhanced areas could be seen in the tumor, and the circumference of the lesions was not enhanced uniformly in 2 cases. Conclusion CT findings of pleomorphic adenoma of palate have some characteristics, which can be helpful for preoperative diagnosis and treatment.
