摘　　要：目的:探讨先天性颈部甲状腺缺如伴舌根部异位甲状腺CT诊断价值。方法:回顾性分析2013年4月~2023年10月晋江市医院收治的15例先天性颈部甲状腺缺如伴舌根部异位甲状腺患者的临床症状、甲状腺激素、超声及CT影像等资料。结果:15例患者以成年女性为主,超声、CT表现:颈前区甲状腺缺如,异位甲状腺均位于舌根正中位置,圆形、椭圆形或不规则形,直径约2.0~3.5cm,CT平扫CT值约63~153Hu,增强扫描显示增多增粗供血动脉,病灶实性部分明显强化,廓清缓慢,囊变坏死区无明显强化;12例甲状腺功能减低,3例甲状腺激素正常,无一例甲状腺功能亢进;病灶大小与口咽部横截面积呈负相关,与临床症状呈正相关,P<0.05。2例病理结果为结节性甲状腺肿,1例乳头状癌,其余12例定期随访无明显变化。结论:颈前区甲状腺缺如伴舌根部高密度肿物需高度怀疑异位甲状腺,CT典型影像表现有助于明确诊断,为临床治疗提供参考依据。Objective:To investigate the diagnostic value of CT findings for cervical thyroid congenital absence with ectopic lingual thyroid.Methords:Retrospectively analyzed of clinical data of 15 patients with ectopic lingual thyroid admitted to Jinjiang Municipal Hospital from April 2013 to October 2023.Results:15 patients were mainly adult females.Ultrasound and CT findings:absence of thyroid in the anterior neck area,ectopic thyroid located in the center of the tongue root,circular,elliptical or irregular in shape,with a diameter of about 2.0-3.5cm.CT plain scan CT value were about 63-153Hu,enhanced scanning shows increased and thickened blood supply arteriesand,the solid part were significantly enhanced and slow washout,the cystic necrotic area were no enhancement.12 cases of hypothyroidism,3 cases of normal thyroid hormones,and none of hyperthyroidism.The lesion size was negatively correlated with oropharyngeal cross-sectional area,and positively correlated with clinical symptoms,P<0.05.2 cases showed nodular goiter,1 case had papillary carcinoma,and the remaining 12 cases showed no significant changes during regular follow-up.Conclusion:High-density mass in the tongue root with thyroid deficiency in the anterior cervical region may highly suspicious of lingual ectopic thyroid.Typical CT imagings help with diagnosis and aclinical treatment.
