Abstract

Tuberculosis is a global disease with a high prevalence rate in the Philippines. Frank hemoptysis often occurs later in the disease and is usually not massive since the availability of anti-Koch’s treatment. However, Rasmussen’s aneurysm, a pulmonary vascular complication secondary to tuberculosis from the weakening of the pulmonary arterial wall adjacent or within a tuberculous cavity, can be an uncommon cause of massive and potentially fatal hemoptysis.

A 35-year-old male patient presented with episodes of hemoptysis while being treated for pulmonary tuberculosis for two weeks. An episode of massive hemoptysis of ~400ml prompted his admission. Chest tomography with contrast showed bronchiectatic changes, cavitary formation, and an aneurysmal dilatation of the anterior segmental artery of the left upper lobe. He was diagnosed with Rasmussen’s aneurysm. A multidisciplinary team consisting of pulmonologists, interventional radiologists and thoracic surgeons planned for a surgical intervention as coil embolization was deemed to be difficult due to the wide neck character of the aneurysm. On re-admission after patient optimization, repeat chest tomography showed interval regression of pulmonary cavity with thrombosis of the previously identified Rasmussen’s aneurysm. Patient completed his 6-month antitubercular treatment with no further episodes of hemoptysis.

In patients with tuberculosis, hemoptysis results from involvement of the parenchyma, bronchiectasis, or erosion of residual cavities. Hemoptysis from the rupture of a dilated vessel such as Rasmussen’s aneurysm is a rare cause. Chest tomography with contrast is the imaging modality of choice as it demonstrates the focal pulmonary artery dilatation. Embolization or surgical lobectomy are typically utilized to control the bleeding. However, treatment with anti-tuberculous regimen may result already in regression and eventual thrombosis of the aneurysm. Watchful monitoring is imperative as massive hemoptysis may recur; radiologists and surgeons must be available at any time in case intervention is required.
