摘要
目的探讨静脉内平滑肌瘤病(IVL)的临床表现与影像学特点,以期提高对该病的诊断水平。方法回顾性分析9例经手术病理证实的IVL患者的临床及影像学资料,分析其临床表现、X线、超声、CT及核磁共振成像特点。结果 9例患者中5例为首次发病,4例为复发患者。5例有子宫肌瘤病史。所有患者初发或复发病程中累及下腔静脉。7例患者病程中肿瘤通过下腔静脉进入心脏,其中6例经盆腔血管进入下腔静脉。首发症状4例表现为心慌气短,2例为下肢肿胀,2例为腹胀,1例为月经量增多。超声表现为盆腔(子宫)和(或)受累静脉及心腔内低回声占位,其内可见血流。CT表现为相应部位低密度占位,增强后不均匀强化。核磁共振成像表现为相应部位等T1稍长T2信号占位,静脉内流空信号消失。结论静脉内平滑肌瘤病具有特定的临床病史及好发部位。影像学检查对该病的早期诊断、手术计划制定和随访评估具有重要价值。
Objective To explore the clinical features and imaging findings of intravenous leiomyomatosis (IVL).Method The clinical features and imaging findings of 9 patients with pathologically confirmed IVL were retrospectively analyzed.Results Out of these 9 patients,there were 5 first-episode patients and 4 recurrent patients.Five patients had a history of uterine leiomyoma.Inferior vena cava (IVC) were involved in all 9 patients.The tumor extended through IVC into right heart chamber in 7 patients,among whom tumo...
