One rare but serious cause of hemoptysis in TB patients is the development of pulmonary artery pseudoaneurysms, known as Rasmussen aneurysms, which typically arise within or adjacent to tuberculous cavitary lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>\n                      We report the case of a 57-year-old male patient who was diagnosed with MDR-TB in July 2024, confirmed by phenotypic resistance against rifampicin and isoniazid. According to WHO recommendations treatment with the BPaLM regimen (bedaquiline, pretomanid, linezolid, and moxifloxacin) was initiated in early August 2024 and was administered according to an extended 9-month schedule due to clinical considerations. After approximately seven months of therapy, the patient was re-hospitalized in March 2025 due to hemoptysis. A thoracic photon counting CT scan revealed regressing bilateral cavitary lesions. During the same month, a pseudoaneurysm arising from a subsegmental pulmonary artery within a cavity\u2014consistent with a Rasmussen aneurysm\u2014was identified. Successful embolization of the feeding vessel was performed under angiographic guidance. Post-interventional bronchoscopy showed minimal residual bloody secretions at the embolization site but no evidence of active bleeding after thorough irrigation. At that time, pending cultures for\n                      <jats:italic>M. tuberculosis<\/jats:italic>\n                      finally converted negative.
