Leiomyosarcoma is a rare tumor of mesenchymal origin usually affecting the inferior vena cava. Early diagnosis is essential before surgical resection, which is the only therapeutic modality that prolongs patients' survival. Ultrasonography, computer tomography, and magnetic resonance imaging are the main imaging modalities in this case. Combined with guided biopsies, they form the mainstay of reliable diagnosis. We report a case with retroperitoneal tumor arising from the middle segment of the inferior vena cava. Radiological examination revealed retroperitoneal tumor and helped to choose surgical treatment. Histopathological examination confirmed the diagnosis of leiomyosarcoma of the inferior vena cava.
平滑肌肉瘤是一种罕见的间叶组织来源的肿瘤，通常影响下腔静脉。在进行外科切除之前进行早期诊断至关重要，因为这是唯一可以延长患者生存时间的治疗方式。超声、计算机断层扫描和磁共振成像都是这种情况下的主要影像学检查方法。结合引导活检，它们构成了可靠诊断的基础。我们报告了一例起源于下腔静脉中段的腹膜后肿瘤。放射学检查显示了腹膜后肿瘤，并有助于选择手术治疗。组织病理学检查证实了下腔静脉平滑肌肉瘤的诊断。
