Tumors of the inferior vena cava are rare, and most of these are leiomyosarcomas. They are most frequent in the sixth decade of life, with a female predominance. We present a 45-year-old male patient with a tumor involving the entire extent of the inferior vena cava. Computerized tomography revealed a heterogeneously enhancing mass with marked expansion of the inferior vena cava with extraluminal extension. Computerized tomography--guided biopsy of the extraluminal component showed features of a fasciculated spindle cell tumor positive for vimentin, smooth muscle actin, and calponin and negative for S-100 antigen. We discuss the clinical presentation imaging findings and review the literature.
下腔静脉肿瘤较为罕见，其中大多数是平滑肌肉瘤。它们在60岁左右最为常见，女性居多。我们报告一例45岁男性患者，其肿瘤累及下腔静脉全长。计算机断层扫描显示一个不均匀强化的肿块，下腔静脉明显扩张并伴有腔外延伸。计算机断层扫描引导下对腔外成分进行活检，结果显示为束状梭形细胞瘤，波形蛋白、平滑肌肌动蛋白和钙调蛋白呈阳性，S-100抗原呈阴性。我们讨论了临床表现、影像学表现并复习了相关文献。
