Hemoptysis is a known complication of active or old burnt-out pulmonary tuberculosis (PTB). The common causes of hemoptysis in PTB patients include tubercular reactivation, bronchiectasis, aspergilloma, and vascular complications such as hypervascularity from bronchial arteries, arteriovenous fistula formation, and pseudoaneurysms. Massive hemoptysis in PTB patients is often secondary to a vascular complication and usually originates from the bronchial circulation (95%) rather than pulmonary circulation. Being rare, Rasmussen's aneurysm (pseudoaneurysm arising from pulmonary arteries) which is a potentially treatable cause for hemoptysis is not looked for and is often missed. Here, we report a case of 70-year-old male PTB patient with massive hemoptysis where the cause of bleeding was a rare Rasmussen's aneurysm.
A 70-year-old male patient presented to the emergency room with a 1-day history of coughing up 10 cups filled with blood. He was a k/c/o PTB (sputum smear 1 +positive for acid-fast bacilli, cartridge-based nucleic acid amplification test-rifampicin-sensitive Mycobacterium tuberculosis detected). On clinical examination, the patient was diaphoretic and distressed. His chest auscultation revealed crepitations in the right axillary and infrascapular area. Examination of other systems was unremarkable. He was anemic with a hemoglobin of 6 g/dL and hypotensive with a blood pressure of 96/50 mmHg. The patient was resuscitated and was transfused with 4 units of packed red blood cells to a hemoglobin level of 10 g/dL. A contrast-enhanced computed tomography (CT) of the thorax was done to find the cause of hemoptysis which revealed dumbbell-shaped bilobulated aneurysm arising from the right posterior basal artery branch of the right pulmonary artery. Larger content of the aneurysm was in the form of noncontrast-enhancing subtotal thrombus [Figure 1]. The bilobed lesion was collectively measured 84 mm × 74 mm. The lateral half lobe seen in the right basal region was measured 55 mm × 45 mm with patent-enhancing artery branch in it. The medial half lobe was measured 48 mm × 34 mm and seen in the left paraesophageal region inferior to the carina causing displacement of the carina [Figure 2]. The bronchial arteries were not enlarged, and no active contrast extravasation was detected from them. After resuscitation, the patient was referred to cardiothoracic vascular surgeon, and selective endovascular coil placement was done with occlusion of the pulmonary aneurysm. The patient's hemoptysis was resolved over the next 12 h. The patient was treated with a full course of antitubercular therapy. The patient is stable and under regular follow-up at our chest outpatient department.

Fritz Waldemar Rasmussen, a Danish physician, first described 11 cases of pulmonary aneurysms in patients with tuberculosis in 1868. Although it is reported in 5% of autopsy series of patients with tubercular cavities, only a few clinical case reports exist in literature.,,, In pulmonary TB patients after ruling out active infective etiology, the cause of hemoptysis is generally looked for in the bronchial arteries, especially in cases with massive hemoptysis. Bronchial arteries in such patients get hypertrophied and enlarged and show rich bronchopulmonary communications, which are the usual source of bleed. Bronchial artery embolization using various substances such as gel foam, pva-poly vinyl alcohol (PVA) embolization particles, and coils, has been used to control massive hemoptysis. If no abnormal bronchial arteries are found, then surgical lobectomy is considered for the control of life-threatening bleed. Rasmussen's aneurysm, though rare, if present, can be another treatable cause of hemoptysis in such patients. CT pulmonary angiography is the best investigation to confirm their existence and should be done in all PTB patients presenting with hemoptysis.
