“…Because of the significant role and importance of diagnostic radiology in this case, aiding in timely identification and intervention, it is beneficial to discuss other etiologies of hemoptysis and their findings on imaging. It is necessary to differentiate a Rasmussen aneurysm from a bronchial artery pseudoaneurysm due to different interventional routes of approach for treatment; embolization through the pulmonary artery versus selective cannulization of the bronchial artery, respectively [ 5 ]. A bronchial artery pseudoaneurysm is a very rare, life-threatening disease observed in up to 3.9% of all cases of selective bronchial arteriography in patients with reported hemoptysis [ 15 , 16 ].…”

“…Bronchial-pulmonary and arteriovenous (AV) communications are disposed to rupture through pseudoaneurysm formation [ 13 ]. On CT, AV malformations are typically identified by recognizing the enlarged, tortuous feeding artery and enlarged draining vein [ 5 ]. Imaging for our case identified an adjacent cavitary lesion and absence of a nidus or draining vein, further demonstrating a Rasmussen aneurysm.…”

“…Life-threatening hemoptysis is uncommon. Since 1868, Rasmussen aneurysm, a pseudoaneurysm arising from the pulmonary artery, has been described relatively few times in the literature, with an estimated prevalence of 4%-8%, most often seen in regions of high tuberculosis (TB) burden [1][2][3][4][5][6]. To date, published cases of Rasmussen aneurysm remain low and subsequently underrecognized.…”

Hemoptysis involves compromised pulmonary vasculature of bronchial versus pulmonary arterial origins, with both life-threatening and non-life-threatening causes. Life-threatening hemoptysis is uncommon. To date, published cases of Rasmussen aneurysm remain low and subsequently underrecognized. We report on a 63-year-old male from Mexico with a more than 30-pack-year smoking history, but no history of lung disease, who presented to the emergency department with cough and hemoptysis for one week. A computed tomography angiography (CTA) chest demonstrated a pseudoaneurysm and hemorrhage, consistent with a Rasmussen aneurysm. Interventional radiology performed a pulmonary angiography, and subsequent coil embolization of the tertiary feeding arteries was performed. This case demonstrates a rare pulmonary artery pseudoaneurysm, known simply as Rasmussen aneurysm, that was successfully managed with coil embolization and highlights the importance of considering the disease in the differential diagnosis for patients with hemoptysis.

“…[1] This term has evolved to become a catch-all for any PA bleeding caused by TB, as distinguishing between true aneurysm and pseudoaneurysm on imaging is often not possible, and extravasation from the PA may even be seen without aneurysmal changes. [2] South Africa (SA) has an extremely high prevalence of pulmonary TB, in excess of 1 000/100 000 in some subpopulations, and consequently a high burden of TB-related haemoptysis. [3,4] Haemoptysis can occur during active TB infection, or as a sequel of previous TB infection, and may present as either trivial or life threatening.…”

Rasmussen aneurysms are abnormalities of the pulmonary arterial system caused by tuberculosis (TB). They are associated with a highmortality rate when they cause life-threatening haemoptysis. High TB-prevalence regions have a large burden of TB-related haemoptysisbut often limited resources. This series of 25 patients who presented with life-threatening haemoptysis from current and/or previous TBwere found to have abnormal pulmonary arteries on computed tomography pulmonary angiogram (CTPA), which were judged to belikely contributors to their bleeding, either in isolation or with concomitant abnormal bronchial or systemic vasculature. These patientsunderwent transcatheter placement of Amplatzer vascular plugs in the feeder pulmonary artery. Bronchial and systemic lesions wereaddressed separately as needed. Immediate technical success was achieved in all patients, but four of them experienced intraoperativehaemoptysis related to dislodgement of the occluding platelet plug by the high-pressure automatic injector and wire. At 48 hours after theprocedure, 18 (72%) remained haemoptysis-free. Six of these experienced recurrence within 1 year of their procedure. Pulmonary arteryplacement of an Amplatzer vascular plug is a feasible option for treating bleeding Rasmussen aneurysms, but should be part of a combinedapproach to addressing suspected culprit vascular lesions in all intrathoracic vascular systems.
