患者女性,39岁,因“腰痛伴双下肢肿胀、乏力半个月”入院。体格检查:双下肢明显肿胀,压之可凹,皮温略低。足背动脉搏动尚可。实验室检查未见异常。常规超声检查:下腔静脉及双侧髂静脉明显增宽,管腔内不规则高回声充填,内见少许条状血流信号。下腔静脉下段至双侧髂血管汇入部与盆腔实性肿物关系密切,肿物范围约15.2 cm×10.1 cm,与子宫分界不清,周边及内部可见彩色血流信号,考虑血管平滑肌瘤病可能。右附件区多房隔囊实性肿物,范围约12.7 cm×6.3 cm,与盆腔肿物关系密切,周边可见彩色血流信号,考虑来源于卵巢。超声造影:下腔静脉远段-双侧髂总静脉分叉处腔内不规则强化,向心性延伸,考虑血管平滑肌瘤病,部分节段合并血栓可能。盆腔肿物与子宫肌层同步增强,强度略高于子宫肌层,呈不均匀增强,与子宫肌层同步消退,似与子宫动脉关系密切,考虑血管平滑肌瘤病。右附件区囊实性肿物实性部分可见造影剂灌注,考虑卵巢来源,交界不除外。下肢静脉CT血管造影:下腔静脉腹段、双侧髂静脉及右侧卵巢静脉、双侧肾静脉起始处充盈缺损影,首先考虑血管平滑肌瘤病。子宫体积增大,强化不均匀,多发肌瘤不除外,右附件区多房囊性病灶,性质待定。正电子发射计算机断层显像:腹盆腔静脉内多发低密度灶,伴氟代脱氧葡萄糖(fluorodeoxyglucose,FDG)代谢增高,盆腔囊实性肿物FDG代谢增高,符合平滑肌瘤病表现。子宫增大,形态不规则,伴FDG代谢增高,考虑多发肌瘤可能。行下腔静脉病损切除术+全子宫、双附件切除术。

图2 下肢静脉CT血管造影图像。图a:下腔静脉腹段、双侧髂总静脉、双侧髂外静脉管腔增宽,腔内可见广泛充盈缺损影(箭头);图b:子宫呈整体不均匀强化(箭头);图c:右侧附件区多房囊性病灶,囊性部分未见明显强化(箭头)
