Foreign body aspiration is frequently encountered in young children, in the majority of cases it will not lead to an adverse outcome. However, in case of coin battery ingestion more serious adverse outcomes, including death, have been reported. We present a case with fatal outcome due to exsanguination, of a 2-year-old child with an aberrant right subclavian artery (or arteria lusoria) and coin battery ingestion. Radiological and autopsy findings and relevant literature are discussed.
