摘要
目的探讨卵巢原发性乳头状甲状腺癌的二维及彩色多普勒血流显像特点。方法对2例经病理学检查确诊的卵巢原发性乳头状甲状腺癌进行二维及彩色多普勒血流显像分析,结合文献对其声像图和血流特点进行探讨。结果超声显示盆腔或下腹部囊实性包块,多数包块内部以实性回声为主,伴有多房小囊;少数以囊性成分为主伴有分隔及实性结节,彩色多普勒显示实性部分有血供较丰富的高速低阻血流。2例均没有临床恶变及转移的证据。结论卵巢原发性乳头状甲状腺癌的声像图缺乏明显特征性,必须结合彩色多普勒及其他影像学和实验室检查与其他卵巢肿瘤相鉴别;肿瘤以多房囊实性或多房囊性内有实性成分多见,同时伴有实性部分的低阻动脉血流信号。因此,在超声疑为畸胎瘤的瘤体内测到有明显血流供应的实质或厚分隔成分时,结合临床应高度怀疑卵巢原发性乳头状甲状腺癌。
Objective To evaluate the characteristics of two-Dimensional ultrasonogra phy （ 2 - D ） and color Doppler flow imaging （ CDFI ） in diagnosis of ovarial primary papillary thyroid carcinoma（PTC）. Methods Two-D and CDFI studies were conducted in 2 cases of ovarial PTC confirmed by pathology,and the ultrasonography and blood flow features were discussed in combination with review of the literature. Results Ultrasound showed solidcystic masses in pelvis or lower abdomen, and the majority of the masses were solid with small multilocular cystic component,while the minority were cystic with thick septations and solid component. The presence of a well-vascularied solid component and low resistance blood flow in the central portion of the tumour on CDFI was frequent findings. No evidence of clinical malignancy or metastases was found in the 2 cases. Conclusion The sonographic features of ovarial PTC are nonspecific. They must be combined with the CDFI, other imagings and laboratory data to distinguish PTC from other ovarial tumours. In most cases the tumour is solid with small multilocular cystic component or multilocular cystic with solid component, accompanied with low resistance blood flow in the solid portion of the tumour. So when the presence of a well-vascularized solid component or thick septations in the central part of a cystic teratoma is detected,the ovarial PTC should be highly suspected.
