Post-thoracotomy intercostal artery pseudoaneurysm manifesting as a chest wall metastasis

We describe the case of a 73-year-old male patient with colonic adenocarcinoma pulmonary metastasis. Repetitive wedge resections and a right lower lobectomy were performed to remove multiple metastatic lesions. At follow-up assessment, the patient reported localized thoracotomy site pain progressing with time and unresponsive to oral analgesics. Chest computed tomography (CT) revealed a pseudoaneurysm of 4-cm diameter of the right 5th intercostal artery. The patient underwent embolization of the lumen and was discharged from the hospital after 24  h. Successive CT re-assessment checks were unremarkable.
