Previous studies report limited interest of CT for spontaneous pneumothorax. Aims of this retrospective case series were to describe CT features of this condition and determine if CT features can efficiently localize the perforation site. Dogs that had a spontaneous pneumothorax, CT examination, thoracic surgery, and confirmed lung perforation due to a grass awn were included. Computed tomography studies were reviewed and compared to the surgical findings. \u00a0In 19 of 22 (86.4%) dogs, the pneumothorax or its recurrence were ipsilateral to the perforation site. The perforation site was identified in 21 of 22 (95.5%) dogs and involved the caudal lobes in 20 of 22 (90.9%) cases. The lateralization and the involved lung lobe corresponded to surgical findings in 21 of 22(95.5%) dogs. The perforation site was characterized as a soft tissue attenuating focus lying against an extensive pleural thickening in 21 of 22(95.5%) dogs. An adjacent defect in the visceral pleura was seen in 13 of 22(59.1%) dogs. A grass awn was seen in 11 of 22(50%) dogs. \u00a0The pneumothorax distribution and grass awn position consistently indicated the perforation side in this sample of dogs. The comparison with surgical findings suggests CT might be helpful for future presurgical planning of this etiology for pneumothorax.<\/jats:p>","DOI":"10.1111\/vru.12831","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T11:52:56Z","timestamp":1576151576000},"page":"157-166","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["CT is helpful for the detection and presurgical planning of lung perforation in dogs with spontaneous pneumothorax induced by grass awn migration: 22 cases"],"prefix":"10.1111","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5100-7769","authenticated-orcid":false,"given":"Cl\u00e9ment","family":"Baudin Tr\u00e9hiou","sequence":"first","affiliation":[{"name":"Centre Hospitalier V\u00e9t\u00e9rinaire Languedocia  Montpellier France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Gibert","sequence":"additional","affiliation":[{"name":"Centre Hospitalier V\u00e9t\u00e9rinaire Languedocia  Montpellier France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"S\u00e9riot","sequence":"additional","affiliation":[{"name":"Centre Hospitalier V\u00e9t\u00e9rinaire Languedocia  Montpellier France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antoine","family":"Duni\u00e9\u2010M\u00e9rigot","sequence":"additional","affiliation":[{"name":"Centre Hospitalier V\u00e9t\u00e9rinaire Languedocia  Montpellier France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurent","family":"Blond","sequence":"additional","affiliation":[{"name":"Centre Hospitalier V\u00e9t\u00e9rinaire Languedocia  Montpellier France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,12,12]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.2002.220.1670"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.228.5.733"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2008.00360.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.2004.tb00254.x"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12278"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2011.01854.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.5326\/0390435"},{"key":"e_1_2_7_9_1","first-page":"244","article-title":"Sensitivity, positive predictive value, and interobserver variability of computed tomography in the diagnosis of bullae associated with spontaneous pneumothorax in dogs: 19 cases (2003\u20102012)","volume":"243","author":"Reetz JA","year":"2013","journal-title":"J Am Anim Hosp Assoc"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/vsu.12741"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-950X.2003.00524.x"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.5326\/JAAHA-MS-6520"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/vru.12388"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.77.10.1082"},{"key":"e_1_2_7_15_1","first-page":"535","volume-title":"Miller's Anatomy of the Dog","author":"Bezuidenhout AJ","year":"2013"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.248.4.413"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/jsap.12163"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2004.04022.x"}],"container-title":["Veterinary Radiology &amp;
