摘要 目的分析卵巢透明细胞癌(OCCC)的CT表现。方法回顾性分析22例OCCC(26个病灶)的CT表现,包括肿瘤位置、形态、大小、边界、CT平扫和强化特征及有无肺动脉栓塞等。结果 4例病灶位于于双侧卵巢,18例病灶位于单侧卵巢。肿瘤呈类圆形或类椭圆形,边界清,有包膜,平均最长径(12.54±4.48)cm。26个病灶中,26.92%(7/26)为实性,3.85%(1/26)为囊性,69.23%(18/26)为囊实性。18个囊实性病灶中,12个为单房囊实性,实性成分呈结节状、球状、团片状、云絮状或分叶状向囊内突出,病灶平扫呈等或稍低密度(CT值28~47 HU)。增强扫描2个实性病灶和1个囊实性病灶实性成分动、静脉期均呈明显强化,23个(23/26,88.46%)病灶实性成分呈进行性中度到明显强化。囊实性病灶囊性成分和囊性病灶平扫及增强各期CT值为13~34HU。6例患者伴不同程度肺动脉栓塞。4例患者伴恶性腹腔积液。结论 OCCC好发于单侧,多表现为边界清晰的单房囊实性肿块,实性成分呈多种形态向囊内突出,增强扫描多呈进行性中度到明显强化,同时易伴发肺栓塞。 Objective To observe CT features of ovarian clear cell carcinoma(OCCC).Methods CT manifestations of 22 patients with 26 lesions of primary OCCC were retrospectively analyzed,including the location,shape,size and margin of tumor,features of plain scan and enhancement pattern,as well as combined with pulmonary embolism(PE)or not.Results Four patients had bilateral lesions,and the rest had unilateral lesions.All lesions were round or oval-shaped,had clear borders and were enveloped.The average longest diameter of the tumors was(12.54±4.48)cm.Of the 26 lesions,26.92%(7/26)were solid,3.85%(1/26)were cystic,and 69.23%(18/26)were cystic solid lesions.Of the 18 cystic solid lesions,12 were single-chamber cystic solid,and the solid components were nodular,globular,lamellae-like,cloud-like or lobulated and protruded into the capsule,which in plain scan were equal or slightly low density(CT values was 28-47 HU).The enhancement of 2 solid lesions and 1 solid component of cystic solid lesion markedly enhanced in both arterial and venous phases,while 23 lesions(23/26,88.46%)showed progressive moderate to significant enhancement of solid components.CT values of cystic component of cystic solid lesions and cystic lesions ranged from 13-34 HU in plain and enhanced CT.Six patients had different degrees of PE.Malignant peritoneal effusion was found in 4 patients.Conclusion On CT scans,OCCC is usually unilateral,often appears as smooth unilocular cystic masses with solid protrusions,the solid portion with persistent mild to moderate enhancement after contrast injection.Patients with OCCC tend to combine with PE.
