Look Past the Bleed! A Case of Non-Traumatic Thoracic Aortic Pseudoaneurysm Presenting as Haemoptysis.

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.

LEARNING POINTS

Recognise haemoptysis as the manifestation of thoracic aortic pseudoaneurysm.Early diagnosis and treatment are crucial due to high rate of complications and mortality.Trauma and cardiovascular surgery are the most common cause for thoracic aortic pseudoaneurysm; however, sometimes it can occur due to atherosclerosis.
