上腔静脉综合征致”假性“骨转移（Bone pseudo-metastases in superior vena cava syndrome）。

CLINICAL HISTORY：

临床病史：

A 46-year-old woman with history of rectal cancer stage IV diagnosed in 2013, treated with an anterior rectal resection followed by adjuvant chemo and radiotherapy. She had done multiple chemotherapy treatments to the present date. The disease had metastasized to her lungs but no other sites of metastasis were documented.

患者女，46岁；2013年诊断为直肠癌IV期，接受了手术、辅助放化疗，目前已经做了多次化疗，发现肺部转移但未发现其它部位转移。

胸部CT增强检查：

图1：Innonimate veins obstruction(无名静脉闭塞)

Contrast-enhanced coronal reformatted CT image showing occluded innominate veins (red arrow). There is a chemotherapy catheter placed through the right innominate vein (white arrow).

增强CT冠状位重组示无名静脉闭塞（红箭）；右侧无名静脉内化疗导管留置（白箭）。

图2：Triangular shaped vertebral uptake

Left: unenhanced scan showing no notorious changes of vertebral bodies atenuation (red arrows); Right: post-contrast images with triangular shaped uptake centered to basivertebral foramen (red arrows), secondary to venous stasis and colaterals (white arrowheads)

左图：平扫CT显示椎体密度无明显变化（红箭）; 右图：增强后图像显示椎体的椎基底静脉区的三角形的密度增高（红箭），继发的静脉淤滞和侧支静脉开放（白箭头）。

图3：Triangular shaped vertebral uptake - Sagital reconstruction。矢状位重组图示，椎体后缘三角形的密度增高。

Post-contrast sagital reconstructions showing vertebral bodies triangular shaped uptake centered to basivertebral foramen (red arrows)

增强后矢状位重组图示椎体后缘椎基底静脉呈三角形高密度。

FINAL DIAGNOSIS:Pseudo-bone metastasis (vertebral plexus vascular congestion)

最终诊断：“假性”骨转移（椎静脉丛血管充血）。

注：Pseudo-bone metastasis ， 意译为”假性“骨转移，请各位提供更专业的翻译名词，谢谢！！！
