As an extremely rare entity reported in children, Rasmussen???s aneurysm is an inflammatory pseudo-aneurysmal dilatation of a branch of the pulmonary artery adjacent to or within a tuberculous cavity. Case. Here, we reported a 9-year-old child with Down syndrome who presented with massive hemoptysis. Endovascular coil embolization was performed for Rasmussen???s aneurysm. During the 2-year follow-up period, she had no further episodes of bleeding. Conclusions. In case of the development of massive hemoptysis in the follow-up of a patient with pulmonary tuberculosis and Down syndrome, this lethal complication should be considered.en10.24953/turkjped.2021.1617info:eu-repo/semantics/openAccesschildDown syndromerasmussen?s aneurysmtuberculosisA rare complication of pulmonary tuberculosis in childhood: Rasmussen's aneurysm in a 9-year-old child with Down syndromeArticle642408411WOS:0008022287000212-s2.0-8513069687235611433Q3Q4
