目的探讨儿童甲状腺癌的超声特点及诊断价值。方法回顾性分析44例经病理证实的儿童甲状腺癌超声表现。结果儿童甲状腺癌声像图表现为3种类型:结节性病灶(77.3%)、结节性病灶合并腺叶弥漫性病变(6.8%)、腺叶弥漫性病变(15.9%)。结节多表现为形态不规则(54.3%)、边界不清晰(63.0%)、周边无声晕(97.8%)、低回声(91.3%)、回声不均匀(82.6%)、内见微小钙化(82.6%)、以Ⅲ型血流为主(82.6%)。微小钙化为儿童甲状腺癌最具特征声像图表现。结论儿童甲状腺癌声像图典型,超声是其首选的有效影像学检查方法。
Objective To investigate the ultrasound features and diagnostic value of thyroid cancer in children. Methods Retrospective analysis of 44 cases of pathologically confirmed thyroid ultrasound in children. Results Thyroid cancer sonography showed three types: nodular lesions (77.3%), nodular lesions with diffuse lesions of the lobes (6.8%), diffuse lesions of the leaves (15.9%). Nodules showed irregular shape (54.3%), unclear border (63.0%), peripheral unpleasant halo (97.8%), hypoechoic (91.3%), echogenic unevenness (82.6% %), Type Ⅲ blood flow (82.6%). Microcalcification of children with thyroid cancer most characteristic sonogram performance. Conclusion Pediatric thyroid cancer typical of sonography, ultrasound is the first choice of effective imaging method.
