Coronary pseudoaneurysm with a superficial mass and accompanying Brucella infection

Abstract

Background and aimsTo our knowledge, no previously reported clinical data of a coronary artery fistula forming a pseudoaneurysm and presenting as a anterior chest wall lump. We reported a rare case of Coronary pseudoaneurysm with a superficial mass and accompanying Brucella infection. The patient was successfully treated with surgery.Materials and methodsThe patient case data was extracted from hospital records.ResultsA 64-year-old male presented with a history of paroxysmal left-sided chest pain and painful anterior chest wall lump. Coronary computed tomography (CT) angiography revealed the RCA pseudoaneurysm that showed a peripherally calcified soft-tissue mass in the anterior mediastinum and communicated with the chest wall lump through intercostal spaces. The patient underwent the resection of chest lump and RCA pseudoaneurysm under cardiopulmonary bypass, along with a combined antimicrobial therapy. The patient was discharged successfully after the surgery.Discussion and conclusionWe report this rare case and highlight the possible origin of the anterior mediastinal mass and anterior chest wall lump as a pseudoaneurysm formed by a coronary artery fistula.
