上淋巴综合征致”假性“骨分散（Bone pseudo-metastases in superior vena ca 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.

症状女，46岁；2013年诊断为直肠癌IV期，接受了手术、特别设计放肌肉注射，以外已经做了多次肌肉注射，见到肺部分散但未见到其它手部分散。

臀部CT强化检查：

左图1：Innonimate veins obstruction(无名微血管闭塞)

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).

强化CT齿状位重组行无名微血管闭塞（T-）；右侧无名微血管内肌肉注射导管留置（青色箭）。

左图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)

左左图：平扫CT显行棱体密度无明显变化（T-）; 所行：强化后左图像显行棱体的棱连续性微血管区的正方形的密度升高（T-），心绞痛的微血管淤滞和侧支微血管开放日（青色箭头）。

左图3：Triangular shaped vertebral uptake - Sagital reconstruction。松田状位重组左法国瓦兹，棱体前缘正方形的密度升高。

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

强化后松田状位重组左法国瓦兹棱体前缘棱连续性微血管排列成正方形高密度。

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

最终诊断：“假性”骨分散（棱微血管映射血管瘙痒）。

注：Pseudo-bone metastasis ， 音译为”假性“骨分散，请各位缺少更从业者的翻译形容词，谢谢！！！
