口腔小唾液腺癌的^(18)F-FDG PET/CT表现

^(18)F-FDG PET/CT manifestations of oral minor salivary gland carcinoma

目的探讨口腔小唾液腺癌的PET/CT表现以提高诊断能力。方法收集30例口腔小唾液腺癌患者术前^(18)F-FDG PET/CT影像资料,并进行回顾性分析。结果30例患者中腺样囊性癌最常见,最好发部位为腭部。CT平扫探测到原发灶9例,病灶同周围正常组织有明确边界者5例。PET/CT能显示所有原发病灶大小、范围、周围组织侵犯及远处转移情况。结论PET/CT能清晰显示原发灶的发生部位、大小、累及范围和转移情况,为口腔小唾液腺癌的术前诊断提供重要帮助。

Objective To investigate the PET/CT findings of oral small salivary gland carcinoma.Methods The^(18)F-FDG PET/CT imaging data of 30 patients with oral minor salivary gland carcinoma were collected and analyzed retrospectively.Results Among the 30 patients,there were 14 cases of adenoid cystic carcinoma and 5 cases of mucoepidermoid carcinoma.The most common site was the upper jaw.CT detected 9 primary lesions in which 5 lesions with clear boundary.PET/CT could show the size,extent,surrounding tissue invasion and distant metastasis of all primary lesions.Conclusions PET/CT can clearly show the location,size,range of involvement and metastasis of the primary focus,and provide help for the preoperative diagnosis of oral minor salivary carcinoma.
