Aortic dissection is a life-threatening condition that might require immediate assessment and therapy. We present the case of a 71-year-old woman with essential hypertension complaining about low back pain; unenhanced thoracic-lumbar spine computed tomography examination (CT) revealed a hyperdense thin line across the aorta with an appearance of "double aortic lumen". Enhanced CT scan confirmed the diagnosis of type B aortic dissection. Radiologists should be familiar with this finding that could be considered a new radiological sign of aortic dissection on unenhanced CT examination.
主动脉夹层是一种危及生命的疾病，可能需要立即评估和治疗。我们报告一例71岁患有原发性高血压的女性患者，她主诉腰痛；未增强的胸腰椎计算机断层扫描（CT）检查显示主动脉上有一条高密度细线，呈“双主动脉腔”外观。增强CT扫描确诊为B型主动脉夹层。放射科医生应熟悉这一发现，其可被视为未增强CT检查时主动脉夹层的一种新的放射学征象。
