摘　　要：目的探讨IgG4相关颈面部疾病的CT与MRI表现。方法回顾性分析19例经病理证实的IgG4相关颈面部疾病患者的影像及临床病理资料并复习相关文献。结果其中10例为双侧泪腺、颌下腺对称性肿大,双侧腮腺多发小囊变,累及右侧眶周组织,双侧颈部多发小淋巴结;6例主要表现为腮腺及颌下腺非对称性结节状病变,病灶MR动态增强的时间-信号强度曲线(TIC)呈平台型,对侧腮腺及颌下腺多发小囊变;3例为双侧泪腺及肾脏对称性肿大。12例病灶信号或密度均较均匀,7例呈结节状的病灶,T1WI略低于邻近唾液腺信号,T2WI及增强扫描与邻近腺体信号接近;行CT检查的病例,CT平扫为等密度,CT增强扫描呈中等较均匀强化。结论IgG4相关颈面部疾病可表现为泪腺和/或唾液腺对侧性肿大,也可表现为唾液腺非对称性结节状改变,信号及密度较均匀,有一定特征性。Objective To investigate the CT and MRI findings of cervicofacial diseases.Methods The imaging and clinic-pathologic data of 19 patients with IgG4 related cervicofacial diseases who have been pathologically diagnosed were analyzed retrospectively and the related literatures were reviewed.Results Among 19 cases,10 cases showed symmetry enlargement of bilateral lacrimal glands and submandibular glands,multiple small cysts in bilateral parotid gland,right periorbital tissues involved and multiple small lymph nodes at bilateral neck,6 cases showed asymmetrical nodular lesions of parotid and submandibular glands,platform-type time-intensity curve of MR dynamic enhancement of the lesion,and bilateral multiple small cysts of parotid and submandibular gland;3 cases showed bilateral symmetry enlargement in lacrimal gland and kidneys.The lesion signal or density of 12 cases were uniform,7 cases showed nodular lesion,the signal was slightly lower on T1WI than that of the adjacent salivary gland,and the signal were close to the adjacent gland on T2WI and enhanced scan.For the cases who received CT scan,equal density was shown on plain CT,and moderate uniform enhancement was shown in enhanced CT scan.Conclusion IgG4 related cervicofacial diseases can manifest as symmetry enlargement in lacrimal gland and/or salivary glands or asymmetric nodular changes in salivary glands,with uniform signal and density and characteristic in CT and MRI.
