Due to the lack of improvement, it was referred to the Imaging Diagnostics Laboratory of the Department and Clinic of Surgery for a computer tomography scan of the thoracic cavity. The examination revealed the presence of air in the pericardial sac, a pneumopericardium, along with pulmonary emphysema. A few minutes after the examination, the rabbit developed circulatory and respiratory failure and died. Necropsy confirmed the presence of a pneumopericardium and pulmonary emphysema, and revealed, in the tracheal lumen, the presence of a tumor histologically consistent with hemangioma. A spontaneous pneumopericardium occurs when air from the respiratory system moves into the pericardial sac. This is the first case of the simultaneous occurrence of tracheal hemangioma and a pneumopericardium in a rabbit.<\/jats:p>","DOI":"10.3390\/ani12151907","type":"journal-article","created":{"date-parts":[[2022,7,26]],"date-time":"2022-07-26T22:03:42Z","timestamp":1658873022000},"page":"1907","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Tracheal Hemangioma Causing Lung Emphysema and Pneumopericardium in a Rabbit\u2014A Case Report"],"prefix":"10.3390","volume":"12","author":[{"given":"Ma\u0142gorzata","family":"Kandefer-Gola","sequence":"first","affiliation":[{"name":"Department of Pathology, Division of Pathomorphology and Veterinary Forensics, Faculty of Veterinary Medicine, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kacper","family":"\u017bebrowski","sequence":"additional","affiliation":[{"name":"Department of Pathology, Division of Pathomorphology and Veterinary Forensics, Faculty of Veterinary Medicine, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafa\u0142","family":"Ciaputa","sequence":"additional","affiliation":[{"name":"Department of Pathology, Division of Pathomorphology and Veterinary Forensics, Faculty of Veterinary Medicine, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0294-3777","authenticated-orcid":false,"given":"Wojciech","family":"Borawski","sequence":"additional","affiliation":[{"name":"Department and Clinic of Surgery, Faculty of Veterinary Medicine, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4071-242X","authenticated-orcid":false,"given":"Eleonora","family":"Brambilla","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Science, University of Milan, Via dell\u2019 Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9445-4235","authenticated-orcid":false,"given":"Valeria","family":"Grieco","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine and Animal Science, University of Milan, Via dell\u2019 Universit\u00e0 6, 26900 Lodi, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"188","DOI":"10.1016\/j.ijscr.2016.04.052","article-title":"Tension pneumopericardium in blunt thoracic trauma","volume":"24","author":"Lopes","year":"2016","journal-title":"Int.
