摘 要: | 目的探讨甲状腺乳头状癌的多层螺旋CT(MSCT)表现及特征。方法回顾性分析2013年5~6月期问四川大学华西医院甲状腺外科收治的35例甲状腺乳头状癌患者的术前MSCT资料,观察其影像学表现与特征。结果35例患者中,24例(68.6%)为单发病灶,11例(31.4%)为2~3个病灶;22例(62.9%)出现颈部淋巴结转移。MSCT共计显示甲状腺乳头状癌病灶48个,有29.2%(14/48)的病灶位于左叶,有70.8%(34/48)的病灶位于右叶;病灶最大径0.4~5.8cm,平均1.3cm;有39.6%(19/48)的病灶密度不均匀,有25.0%(12/48)的病灶形态不规则,有47.9%(23/48)的病灶边缘模糊欠清,有18.8%(9/48)的病灶显示为乳头状强化瘤结节,有10.4%(5/48)的病灶瘤周出现“强化残圈”征,有22.9%(11/48)的病灶侵犯周围脂肪间隙或邻近器官。有35.4%(17/48)的病灶出现钙化,其中有76.4%(13/17)呈细粒状钙化,11.8%(2/17)呈粗钙化,11.8%(2/17)呈混合性钙化。结论甲状腺乳头状癌的MSCT表现具有一定的特征性,可为临床治疗方案的选择提供影像学依据。

Abstract: | Objective To explore the manifestations and features of multi-slice spiral CT (MSCT) in the diagnosis of papillary thyroid carcinoma (PTC). Methods Preoperative MSCT data of 35 cases of PTC proved by operation and pathology in our hospital form May. to Jun. in 2013 were observed retrospectively, to analyze the manifestations and characteristics of MSCT for it. Results Of 35 patients with PTC, MSCT totally showed 48 lesions, 68.6% (24/35) of patients with single lesion, 31.4% (11/35) of patients with 2-3 lesions, and 62.9% (22/35) of patients with lymph node metastasis. Of the 48 lesions, 29.2% (14/48) of lesions located in the left lobe, 70.8% (34/48) of lesions located in the right lobe; the lesions' maximum diameter were 0. 4 5.8 cm, with the average maximum diameter of 1.3 cm. There were 39. 6% (19/48) of lesions with uneven density, 25.0% (12/48) of lesions with irregular shape, 47.9% (23/48) of lesions with blurred edges, 18.8% (9/48) of lesions had papillary enhanced tumor nodules, I 0.4% (5/48) of lesions had peritumoral incomplete enhanced ring sign, 22. 9% (11/48) of lesions invaded surrounding tissue or organs. There were 35.4% (17/48) of lesions had calcification, in which 76.4% (13/17) of lesions were fine granular calcification, 11.8% (2/17) of lesions were mixed calcification, and 11.8% (2/17) of lesions were coarse calcification. Conclusion MSCT manifestations of PTC have certain characteristics, which can provide imaging basis for clinical treatment options. |
