False Aneurysm of the Ascending Aorta Caused by a Sternal Wire
A 75-year-old man was admitted to our hospital with chest pain and B symptoms. Three years earlier, he had undergone radio- and chemotherapy because of a malignant lymphoma of the left femur. During this time, the patient was clinically in remission. On admission, echocardiography revealed pericardial effusion and a 4-cm tumor in the right atrial appendage. Staging was completed with computed tomography of the thorax and abdomen, which confirmed the findings from the ultrasound examination. Open biopsy via median sternotomy was performed to make a diagnosis; the histological diagnosis was recidivation of the lymphoma. Postoperatively, the patient complained repeatedly of pain in the sternal region. Chest x-ray (Figure 1) showed that the fourth sternal wire protruded into the anterior mediastinum. ECG-gated computed tomography of the chest after intravenous contrast administration (Figure 2) depicted a false aneurysm between the 2 wires of the sternum cerclage originating from the anterior circumference of the ascending aorta.
