Enhancement patterns of visceral venous collaterals are well documented in cases of superior vena cava obstruction. Only recently has intraosseous venous collateral enhancement been described. We describe an unusual case of vertebral marrow enhancement in the lower thoracic spine related to venous collateral circulation caused by an incidental hemiazygos thrombus. Misinterpretation of this finding can lead to the erroneous interpretation of sclerotic bone metastases.

上腔静脉阻塞病例中内脏静脉侧支循环的强化模式已有充分记录。骨内静脉侧支循环强化直到最近才被描述。我们描述了一例因偶然发现的半奇静脉血栓导致静脉侧支循环引起的下胸椎椎体骨髓强化的罕见病例。对这一发现的错误解读可能导致对硬化性骨转移的错误诊断。
