Rasmussen’s aneurysm is a false inflammatory aneurysm of a branch of the pulmonary artery within or adjacent to a tuberculous cavern or other excavated lung lesion, whose rupture may lead to massive hemoptysis. Our patient, who was at 35 days of antibacillary treatment, complicated by a medium abundance hemoptysis revealing a false Rasmussen’s aneurysm confirmed by chest CT angiography, and treated by embolization of the right inferior lobar artery during a chest angiography. The course was marked by resolution of the hemoptysis. Rasmussen’s aneurysm remains a rare cause of massive hemoptysis that requires urgent management, relying firstly on endovascular treatment.
