【摘要】 目的:探讨甲状腺乳头状癌的声像图表现。方法:对我院2000年1月~2008年6月经手术病理诊断为甲状腺乳头状癌的96例患者的声像图资料作回顾性分析。结果:本组96例甲状腺乳头状癌超声诊断准确率为92.7%,其声像图特点为:①肿瘤形态呈圆形、类圆形或不规则形;②肿瘤边缘不清无包膜,呈小毛刺状或"小米粒样"向瘤周突出;③成人肿瘤以低回声为主,儿童可为等回声;④肿瘤靠近被膜时可致局部被膜不连续;⑤近半数患者可显示散在的点状钙化或密集的砂粒样钙化;⑥癌结节血供丰富,发生率86.2%;⑦术前超声检查颈部淋巴结转移灶与原发灶回声相似,多见于直径大于1 cm的患者,发生率15.6%。微小甲状腺乳头状癌生长速度十分缓慢,随访观察没有诊断意义。结论:超声对甲状腺乳头状癌的诊断具有较高的临床应用价值。更多还原

【Abstract】 Objective:To investigate the images of thyroid papillary adenoid cancer.Methods:Ninety-six cases were analyzed which have been confirmed by histopathology after operation from Jan 2000～Jun 2008.Results:The accurate rate of ultrasonic diagnosis was 92.7%.The characters of image were: ①the shapes of tumors were round,similar round and irregular;②no capsule and no clear border echo in the tumors;③the internal echo of tumors were low level echo in adult and medium echo in children;④ the tumor near the capsule of thyroid can damage the local capsule;⑤scatter or concentrated minor calcification were observed in 50% of cases;⑥about 86.2% of tumors had rich blood flow;⑦ the echo of cervical lymph-node was similar with tumor in 15.6% of patients.The tumors grow very slowly,follow investigation was meaningless.Conclusions: The ultrasonic diagnosis of thyroid papillary adenoid cancer possesses clinical value.更多还原
