3例脉络膜转移性CC-RCC均为男性,例1和例3均为62岁,例2为51岁,平均58岁,均表现为右眼前黑影伴视力下降,病程分别为6月,1月和4月。术前检查视力均为右眼前手动,右眼底见视网膜下隆起肿块伴视网膜脱离。3例B超均显示右眼球内隆起肿物,例1和例2位于后极部,例3位于鼻侧球壁,中等回声,大小7.1~8.4 mm × 15.5~18.2 mm,均伴表面视网膜脱离,例3伴挖空征及脉络膜凹陷征,考虑脉络膜黑色素瘤(图1 )。例2两年前行左肾癌手术,1年前右肺上叶转移,术前胸部C T显示双肺多发结节,右侧为著,大者2 cm ×2 cm。例1术前胸部CT显示两肺内多个小结节影,大部分位于两肺外带,结节边界尚清晰,符合肺转移瘤表现。3例均在我院眼科全身麻醉下进行了右眼球摘除及义眼座的植入(表1)。

2.1.2 眼眶转移性CC-RCC
2例眼眶转移性CC-RCC中例4为女性,56岁,右眼红肿伴眼球突出2个月,2个月前外院行右肾CC-RCC切除手术,术前CT显示右眶外上方3 cm ×4 cm软组织肿块,涉及眶顶及外侧肌锥外与中颅底,伴眶顶壁、外侧壁与蝶骨大翼骨质破坏(图2 )。PET-CT提示右肾癌术区未见明显肿瘤复发,右眼眶外侧壁转移并侵及右侧额骨。术前右眼矫正视力0.6,右眼球突出,上转运动受限,眼球下移。例4在我院全身麻醉下行右眶颅联合肿物摘除术(表2)。
例5,男性,65岁,左眉弓肿物3年,渐大。7年前左肾CC-RCC切除术,术后靶向药物(多吉美)治疗,半年前“肾癌肺部转移”行胸腔镜手术。术前MRI示左眶顶上眼睑皮下一椭圆形结节肿块影,大小2.2 cm ×2.4 cm ×2 cm,紧贴眼球前上壁,眼球向下移位。术前左眼视力0.1,左眼眉弓处扪及质硬隆起肿物2 cm ×1 cm,界清,眼球下移伴上睑下垂。例5在我院全身麻醉下行左眼眶肿物摘除术(表2)。
图2 右眼眶转移性CC-RCC患者(例4):冠状位和水平位CT显示右眶外上方3 cm ×4 cm软组织肿块,涉及眶顶及外侧肌锥外与中颅底,伴眶顶壁、外侧壁与蝶骨大翼骨质破坏

2.3 治疗和随访
2.3.1 脉络膜转移性CC-RCC
例1术后腹部CT示左肾下部见一椭圆形软组织影,大小6.5 cm ×5.8 cm ×8.9 cm,左肾门下部肾静脉内见充盈缺损影,诊断左肾癌伴左肾静脉癌栓形成,后在当地医院行左肾摘除术,病理检查证实为左肾CC-RCC。术后2年患者因肺转移死亡。例2眼部手术后因同时肺部转移行放疗和中医治疗,20个月后死亡。例3术后PET-CT检查发现左肾占位,在当地医院行左肾摘除术,术后病理示左肾CC-RCC,肿瘤大小约4.5 cm ×4 cm ×3 cm。术后未行特殊治疗,随访至今2 3个月无复发和转移(表1)。CC-RCC
