Look past the bleed! A case of non-traumatic thoracic aortic pseudoaneurysm presenting as haemoptysis

Abstract

Introduction: Aortic pseudoaneurysms are a type of contained rupture where most of the aortic wall is breached, leaving only a thin rim of the remaining wall or adventitia to hold the blood. This condition carries a high risk of rupture and potentially fatal complications. Typically, patients present with chest pain; haemoptysis can also occur, though rarely. Case description: A 64-year-old male who presented with two episodes of haemoptysis, with no history of cardiovascular surgery or trauma. A chest computerized tomography (CT) followed by an aortogram revealed a thoracic aortic pseudoaneurysm and the patient underwent surgical aortic repair without any complications. This case underscores the rare presentation of thoracic aortic pseudoaneurysm. Discussion: Haemoptysis is a rare manifestation of thoracic aorta pseudoaneurysm and can be a warning sign of impending rupture. Haemoptysis may occur due to formation of aortopulmonary fistula or direct erosion of pseudoaneurysm into lung parenchyma. Conclusion: It is imperative for clinicians to recognise such manifestations early for prompt diagnosis and prevention of complications.
