1) The haemoptysis usually originates from the bronchial arteries but rupture of an underlying Rasmussen aneurysm might cause recurrent haemoptysis, sometimes with fatal consequences.
Selective embolisation of the Rasmussen aneurysm pedicle with one 3 mm x 5 cm and two 3 mm x 4 cm helical coils (Cook, Bloomington, USA) via a 5 Fr catheter achieved complete exclusion of the aneurysm.
5) Rasmussen aneurysm is a rare complication (in 5% of autopsied patients with cavitatory tuberculosis(6)) caused by pulmonary artery wall weakening owing to the adjacent cavitatory tuberculosis.
8) Additionally, it may assist in identifying signs suggesting that the pulmonary artery is the source of bleeding, such as the presence of a proximal cavity, visualisation of a pulmonary artery bordering a cavity and a Rasmussen aneurysm.
Rasmussen aneurysm is a common cause of recurrent and sometimes massive haemoptysis in patients with cavitatory pulmonary tuberculosis.
