Abstract
Haemoptysis is concerning for both patient and healthcare provider and points to the presence of severe underlying lung disease warranting investigation. Approximately 8% of patients with pulmonary tuberculosis (PTB) infection will experience haemoptysis at some point during their life ([1;2]). The aetiology of haemoptysis in the setting of PTB is diverse and may occur during active or following prior PTB infection due to pulmonary complications. We describe the case of a 33-year-old female who presented with massive haemoptysis on two separate occasions within a five-month period. Her background history included PTB 6 years prior and subsequent post-TB bronchiectasis with a destroyed left lung, and the development of apical mycetoma's. Despite numerous pre-existing aetiologies that could account for haemoptysis in this patient, on this admission, a newly identified ruptured Rasmussen's aneurysm was identified by angiography and successfully treated with arterial embolization. This report serves to highlight the multitude of reasons for haemoptysis in a patient with post PTB lung destruction and the associated diagnostic challenges that may be present. In particular, we highlight the Rasmussen's aneurysm, a rare entity, as a hidden cause of haemoptysis, where despite extensive parenchymal lung disease identified on chest radiography, specialised imaging is needed to confirm the diagnosis.
