Abstract:
Objective To study the enhanced patterns of papillary thyroid carcinoma (PTC)on contrast-enhanced ultrasound(CEUS),and explore the relationship between the degree of enhancement and extracapsular invasionand cervical lymph node metastasis of the tumor.Methods Seventy-three PTCs in 61 patients selected for thyroid surgery underwent conventional ultrasound andcontrast-enhanced ultrasound. The enhanced patterns were analyzed.The differences between different degree enhancement and extracapsular invasion and cervical lymph node metastasis of PTCs were compared.Results Seventy-three PTCs enhanced patterns showed that 52(71 .2%)nodules with hypoenhancement,13(1 7.8%)nodules with isoenhancement,8 (1 1 .0%)nodules with hyperenhancement.Twenty-three (44.2%,23/52 )nodules with extracapsular invasion in hypoenhancing patterns,and 1 5 (71 .4%,1 5/21 ) nodules with extracapsular invasion in isoenhancing or hyperenhancing patterns.There were significant differences between them(P <0.05).Twenty-five (48.1 %,25/52 ) nodules with cervical lymph node metastasis in hypoenhancing patterns,and 13 (61 .9%,13/21 ) nodules with cervical lymph node metastasis in isoenhancing or hyperenhancing patterns,there was no significant difference between them(P >0.05 ).Conclusions The degree of enhancement are correlate to invasiveness in PTCs,PTCs with isoenhancement or hyperenhancement patterns were more often with extracapsular invasion.
