Tumors arising from veins are rare, usually present with nonspecific clinical and imaging findings and almost universally show histology of leiomyosarcoma. This twentieth reported case of primary renal vein leiomyosarcoma demonstrates invasion of the renal vein with endoluminal propagation of tumor into the infrahepatic inferior vena cava (IVC), an unreported manifestation. The combination of CT, ultrasound, and angiographic studies allowed differentiation from renal cell carcinoma by suggesting a tumor arising from the renal vein.
源于静脉的肿瘤很罕见，通常表现为非特异性的临床和影像学表现，几乎均显示为平滑肌肉瘤组织学特征。这是第二十例原发性肾静脉平滑肌肉瘤的报道病例，显示肿瘤侵犯肾静脉并经腔内蔓延至肝下下腔静脉（IVC），此为未报道过的表现。CT、超声和血管造影检查相结合，提示肿瘤源于肾静脉，从而有助于与肾细胞癌相鉴别。
