A 61-year-old woman with symptoms of inferior vena caval obstruction was investigated with computed tomography and ultrasound imaging and found to have a tumor of the inferior vena cava. Transvenous biopsy revealed a leiomyosarcoma, which at surgical exploration was considered to be unresectable. Autopsy showed that the tumor extended form its origin in the inferior vena cava just above the left renal vein to the right atrium. Hepatic metastases were documented. This rare tumor has seldom been diagnosed prior to exploratory surgery or necropsy and should be included in the differential diagnosis of inferior vena caval obstruction. The case illustrates the relative ease and efficacy of transvenous biopsy in establishing this diagnosis antemortem.
一名61岁有下腔静脉阻塞症状的女性接受了计算机断层扫描和超声成像检查，发现患有下腔静脉肿瘤。经静脉活检显示为平滑肌肉瘤，手术探查时认为无法切除。尸检显示肿瘤从其起源处，即左肾静脉上方的下腔静脉延伸至右心房。记录有肝转移。这种罕见肿瘤在探查性手术或尸检前很少被诊断出来，应列入下腔静脉阻塞的鉴别诊断。该病例说明了经静脉活检在生前确立这一诊断的相对简便性和有效性。
