Skeletal metastases are frequently observed in various malignancies. In some cases, they are asymptomatic and can be found incidentally in various imaging methods in patients without known malignant tumors. In this case study 2 cases of vertebral perfusion disturbances are presented that imitate vertebral metastatic lesions in computer tomography in the course of superior vena cava thrombosis. The first patient was referred to our clinic for chest and abdominal computer tomography (CT) for staging due to a known tumor in the anterior mediastinum. The second patient was referred for chest CT due to swelling in the upper extremity and neck, with the suspected diagnosis of a tumor or pulmonary embolism. In both cases, CT scans showed metastases suspected lesions in the upper thoracic vertebral bodies. In both cases, additionally, the thrombosis of superior vena cava (SVC) and vena brachiocephalica was confirmed (in the first case due to tumor compression in the upper mediastinum, in the second case due to the presence of pacemaker leads). In control CT scans after anticoagulation treatment, there were no suspected lesions in the vertebral bodies, which confirmed the diagnosis of vertebral perfusion disturbances in the course of SVC thrombosis in both patients. In conclusion, in rare cases of metastases suspected lesions of thoracic vertebral bodies in contrast-enhanced computer tomography among patients with a diagnosis of superior vena cava thrombosis vertebral perfusion disturbances should be included in differential diagnosis protocol.
