探讨卵巢透明细胞癌（OCCC）超声声像图特点，为卵巢透明细胞癌的早期诊断提供依据。

对2005年1月至2017年5月经首都医科大学附属北京友谊医院临床诊治及手术病理确诊为卵巢透明细胞癌的45例患者超声声像图特点进行回顾性分析。

45例卵巢透明细胞癌患者的46个病灶（单侧卵巢病灶44例，双侧卵巢病灶1例）中32个（69.6%）形态规则，14个（30.4%）形态不规则；40个（87.0%）病灶边界清晰，6个（13.0%）病灶边界不清晰。病灶最大径4.8~17.6 cm，平均（10.2±3.4）cm；其中以实性为主的病灶15个（32.6%），以囊性为主的病灶12个（26.1%），囊实混合型病灶19个（41.3%）；彩色多普勒血流成像示28个（60.9%）病灶内血流信号丰富；18个（39.1%）病灶内血流信号不丰富；6例（13.3%）伴腹腔积液。

卵巢透明细胞癌肿瘤病灶较大，以单侧、边界清晰、囊实性改变、血流信号丰富的病灶居多。超声检查及早发现卵巢癌病灶可为患者早期诊断和手术治疗提供依据。

To investigate the ultrasound characteristics of ovarian clear cell carcinoma (OCCC) and provide basis for early diagnosis of OCCC.

Retrospective analysis was performed on 45 patients with OCCC, who were pathologically diagnosed and treated in Beijing Friendship Hospital, Capital Medical University from January 2005 to May 2017.

In forty-five cases of OCCC, forty-six lesions were found (forty-four cases of unilateral ovarian lesions, one case of bilateral ovarian lesion). Among forty-six lesions, thirty-two (69.6%) were regular in shape, fourteen (30.4%) were irregular. Among forty-six lesions, forty (87.0%) had clear margin, six (13.0%) had blurry margin. The maximum diameter of lesion was 4.8-17.6 cm with mean value of 10.2±3.4 cm. Fifteen lesions (32.6%) were predominantly solid, twelve lesions (26.1%) were cystic, and nineteen lesions (41.3%) were mixed. The color Doppler examination showed that twenty-eight (69.9%) lesions had abundant blood flow, while eighteen (39.1%) lesions had little blood flow. Ascites was found in six (13.3%) cases.

OCCC usually appears as a large unilateral mass with mixed component, clear margin and abundant blood flow.Ultrasound examination can play an important role in the early diagnosis of OCCC, and provide valuable information for surgical treatment.
