Primary neuroectodermal renal tumours (PNET) are rare and aggressive neoplasms; thrombosis of the inferior vena cava (IVC) is associated with this entity. We report here the case of a 19-year-old man who experienced a new onset of abdominal pain. A CT scan revealed a large left renal mass, perirenal haematoma and IVC thrombosis. Owing to an acute drop in haemoglobin and subsegmentary pulmonary embolism, he underwent emergency selective renal artery angiography and embolisation of bleeding vessels and IVC filter (IVCF) placement. Once stable, he underwent a left radical nephrectomy and IVC thrombectomy; the pathology report confirmed PNET. 6 months later, imaging revealed a residual tumoral thrombus in the IVCF located in the retrohepatic IVC. The patient underwent removal of this device and the thrombus via a right thoracoabdominal approach. He recovered well and at 4 months, he continues his chemotherapy cycles.
原发性神经外胚层肾肿瘤（PNET）是罕见的侵袭性肿瘤；下腔静脉（IVC）血栓形成与该实体相关。我们在此报告一名19岁男性新发腹痛的病例。CT扫描显示左肾有一个大肿块、肾周血肿和IVC血栓形成。由于血红蛋白急剧下降和亚段肺栓塞，他接受了紧急选择性肾动脉血管造影、出血血管栓塞和IVC滤器（IVCF）置入。病情稳定后，他接受了左肾根治性切除术和IVC血栓切除术；病理报告证实为PNET。6个月后，影像学检查显示位于肝后IVC的IVCF中有残留肿瘤血栓。患者通过右胸腹联合入路取出了该装置和血栓。他恢复良好，4个月时继续进行化疗周期。
