目的探讨卵巢卵泡膜细胞瘤的声像图特征并分析其误诊原因,以提高卵泡膜细胞瘤的术前诊断符合率。方法回顾性分析我院40例(42个)卵泡膜细胞瘤的二维(30例)及彩色多普勒(10例)超声表现,并与病理结果进行对照分析。结果 42个卵泡膜细胞瘤中,32个呈实性(29个低回声、2个等回声、1个高回声),9个呈囊实性,1个呈囊性;实性中9个后方伴衰减;经彩色多普勒超声检查10例中,仅1例内部未见明显彩色血流信号,余9例内部均可见彩色血流信号。术前超声正确诊断为卵巢肿瘤20个(47.62%),但未进一步定性诊断,误诊为恶性肿瘤12个(28.57%)、卵巢囊肿1个、卵巢纤维瘤1个、卵巢占位2个、子宫浆膜下肌瘤5个、阔韧带肌瘤1个。无一例提示卵泡膜细胞瘤。结论卵泡膜细胞瘤以实性为主,低回声、边界清晰及后方伴衰减是其主要的超声表现,需与卵巢恶性肿瘤、卵巢纤维瘤、子宫浆膜下或阔韧带肌瘤等疾病鉴别。
Objective To investigate the characteristics of ovarian amenteal cell tumor and analyze the causes of misdiagnosis so as to improve the coincidence rate of preoperative diagnosis of theca cell tumor. Methods A retrospective analysis of 40 cases (42) in our hospital, two-dimensional (30 cases) and color Doppler ultrasound (10 cases) were performed and compared with the pathological results. Results Of the 42 achondromatocytomas, 32 were solid (29 hypoechoic, 2 unequal, 1 echogenic), 9 were cystic and 1 cystic; With attenuation; color Doppler ultrasound examination in 10 cases, only 1 case no significant internal color flow signals, the remaining 9 cases were visible within the color flow signal. There were 20 ovarian tumors (47.62%) correctly diagnosed before operation, but no further diagnosis was made. Twelve (28.57%) were misdiagnosed as malignant tumors, 1 ovarian cyst, 1 ovarian fibroma, 2 ovarian lesions, Subserosal fibroids 5, 1 broad ligament fibroids. No case of ameloblastoma. Conclusions The majority of ameloblastomas are solid, low echo, clear boundary and attenuated posterior. They are the main manifestations of the disease. They need to be differentiated from malignant ovarian tumors, ovarian fibroids, subserosal or broad ligament fibroids.
