甲状腺孤立性纤维性肿瘤的超声诊断学特征并文献复习

目的探讨甲状腺孤立性纤维性肿瘤的超声诊断学特征。 方法回顾性分析2020年7月29日就诊于济宁医学院附属医院甲状腺外科的1例甲状腺孤立性纤维性肿瘤患者的临床资料和影像学、病理学检查结果,并复习相关文献。 结果患者颈前偏左局限性隆起,甲状腺左叶可触及一明显肿物。超声可见甲状腺左叶一不均质回声团块,大小约5.8 cm×4.0 cm×2.7 cm,界清,形态规则,后方回声衰减,内可及较丰富的分支状血流信号。甲状腺CT平扫及增强扫描可见甲状腺左叶内略低密度影,增强后呈不均匀性延迟强化,呈"快进慢出"的特点。术后病理诊断为孤立性纤维性肿瘤。 结论超声对甲状腺孤立性纤维性肿瘤的大小、形态、内部回声、血流情况具有一定特征性,结合其他检查可提高该病的临床诊断率。

Ultrasonic diagnostic features of solitary fibrous tumors of thyroid and literature review

ObjectiveTo investigate the ultrasonic diagnostic features of solitary fibrous tumor of thyroid. MethodsThe clinical data, imaging and pathological findings of a patient with solitary fibrous tumor of thyroid who was admitted to the Thyroid Surgery Department, the Affiliated Hospital of Jining Medical University on July 29, 2020 were retrospectively analyzed, and relevant literatures were reviewed. ResultsThe patient had a localized bulge on the left front of the neck, and an obvious mass was palpable in the left lobe of the thyroid. Ultrasound showed an inhomogeneous echo and well-defined mass in the left lobe of the thyroid, about 5.8 cm×4.0 cm×2.7 cm with regular shape, attenuation of posterior echo, and abundant braching blood flow signals. Plain CT scans showed a slightly low-density shadow in the left lobe of the thyroid, and it showed uneven delayed enhancement, which was characterized by " fast in and slow out" . The pathological diagnosis of subtotal thyroidectomy was solitary fibrous tumor. ConclusionUltrasound has certain specific features in size, shape, internal echo and blood flow of solitary fibrous tumor of thyroid, which can improve the clinical diagnosis rate of the disease combined with other examinations.
