甲状腺包膜内乳头状癌的超声表现

目的:探讨甲状腺包膜内乳头状癌的超声表现。方法:回顾分析经手术病理证实的95例甲状腺包膜内乳头状癌患者共计97个病灶(经典型68个,滤泡型29个)的彩色超声声像图资料,根据甲状腺超声影像学报告及数据系统(thyroidimaging reporting and data system,TI-RADS)将甲状腺病灶分为良性、良性可能、不确定性、恶性可能及恶性5级。结果:经典型甲状腺包膜内乳头状癌提示恶性的超声表现有微小钙化(41%)及边缘针刺状(15%);滤泡型甲状腺包膜内乳头状癌提示恶性的超声表现有微小钙化(14%)。经典型与滤泡型甲状腺包膜内乳头状癌超声分级为良性、良性可能、不确定性、恶性可能及恶性的比例依次为10%、16%、31%、28%、15%及48%、21%、17%、14%、0。结论:甲状腺包膜内乳头状癌尤其是滤泡型甲状腺包膜内乳头状癌的超声分级多为良性、良性可能或不确定性,少数为恶性及恶性可能。

Ultrasonographic Features of Encapsulated Papillary Thyroid Carcinoma

Objective：To evaluate the ultrasonographic features of encapsulated papillary thyroid carcinoma.Methods：Ultra sonographic features of 95 patients（97 cases of lesions） with encapsulated papillary thyroid carcinoma（68 cases of classical type and 29 cases of follicular type） confirmed by pathology were retrospectively analyzed.Each thyroid nodule was classified into benign,probably benign,indeterminate,possibly malignant,and malignant according to thyroid imaging reporting and data system（TI-RADS）.Results：The ultrasonographic features that suggested malignancy were microcalcifications（41 ％）,spiculated margin（15％） for classical encapsulated papillary thyroid carcinoma,and microcalcifications （14％） for follicular encapsulated papillary thyroid carcinoma.The percentage of benign,probably benign,indeterminate,possibly malignant,malignant classification of classical and follicular encapsulated papillary thyroid carcinoma were 10％,16 ％,31 ％,28 ％,15％ and 48％,21％,17％,14％,0,respectively.Conclusions：Ultrasonographic classification of encapsulated papillary thyroid carcinoma especially for follicular encapsulated papillary thyroid carcinoma are mostly benign,probably benign or indeterminate,and rarely malignant or possibly malignant.
