A case of CLE of the right middle lung lobe predisposing to air trapping, alveolar hyperinflation, and pleural rupture resulting in fatal spontaneous TPT in a 6-month-old mixed breed dog is described. The unique alteration of \u201cbloat line\u201d was observed in this case in addition to compressive atelectasis of all other lung lobes and lack of negative pressure within the thoracic cavity, signifying markedly elevated intrathoracic pressure. Bronchial cartilage hypoplasia and bronchiectasis were confirmed microscopically, which likely led to abnormal dynamic collapse of bronchi during expiration, consequentially leading to increased intrapulmonary pressure, bullous emphysema, and pleural rupture resulting in TPT. TPT consequent to CLE may therefore be considered one of the potential causes of sudden death in young dogs without overt clinical illness.<\/jats:p>","DOI":"10.1177\/104063870701900319","type":"journal-article","created":{"date-parts":[[2011,5,12]],"date-time":"2011-05-12T16:26:52Z","timestamp":1305217612000},"page":"322-325","source":"Crossref","is-referenced-by-count":25,"title":["Congenital Lobar Emphysema and Tension Pneumothorax in a Dog"],"prefix":"10.1177","volume":"19","author":[{"given":"Gopakumar","family":"Gopalakrishnan","sequence":"first","affiliation":[{"name":"Animal Disease Diagnostic Laboratory and Department of Comparative Pathobiology, Purdue University School of Veterinary Medicine, West Lafayette, Indiana 47907."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory W.","family":"Stevenson","sequence":"additional","affiliation":[{"name":"Animal Disease Diagnostic Laboratory and Department of Comparative Pathobiology, Purdue University School of Veterinary Medicine, West Lafayette, Indiana 47907."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2007,5,1]]},"reference":[{"key":"bibr1-104063870701900319","first-page":"321","volume":"23","author":"Amis TC","year":"1987","journal-title":"J Am Anim Hosp Assoc"},{"key":"bibr2-104063870701900319","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9975(89)90015-7"},{"key":"bibr3-104063870701900319","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.2002.tb00035.x"},{"key":"bibr4-104063870701900319","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1996.81.4.1664"},{"key":"bibr5-104063870701900319","unstructured":"Evans HE: 1993.
