目的对比研究甲状腺微小乳头状癌(papillary thyroid microcarcinoma,PTMC)的超声影像表现及其病理基础。方法对39例PTMC患者43个病灶的超声影像表现与病理组织特点进行对照分析。结果超声检查病灶形态是否规则与病理检查病灶有无纤维假包膜上差异无统计学意义(P>0.05);超声检查病灶边界是否清晰与病理检查病灶边缘有无浸润上差异无统计学意义(P>0.05);超声检查病灶内部回声是否均匀与病理检查病灶内部有无囊性变或钙化上差异无统计学意义(P>0.05);超声与病理检查在病灶内有无钙化上差异有统计学意义(P<0.05)。结论超声检查能够较好的反应PTMC病灶的病理组织特点,对其具有较高的诊断价值。
Objective To compare the ultrasonographic manifestations and pathological features of papillary thyroid microcarcinoma (PTMC). Methods 43 cases of PTMC in 39 cases of ultrasound imaging and pathological features of the control group were analyzed. Results Ultrasound examination of the lesion morphology and histopathological examination with or without fibrous pseudocapsules showed no significant difference (P> 0.05); ultrasound examination of the lesion border is clear and pathological examination of the edge of the margin infiltration was no significant difference (P> P> 0.05); Ultrasound examination of the internal echo lesions are uniform and pathological lesions within the cystic lesions or calcification was no significant difference (P> 0.05); ultrasound and pathological examination in the lesion with or without calcification were statistically significant Significance (P <0.05). Conclusion Ultrasound can better reflect the pathological features of PTMC lesions, which has high diagnostic value.
