Most cases are asymptomatic and incidentally detected during a thoracic surgery or autopsy. We report a case of a partial pericardial defect confirmed based on spontaneous pneumothorax.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Presentation of case<\/jats:title>\n                    <jats:p>A 16-year-old boy with left spontaneous pneumothorax showed pneumopericardium on chest X-ray. Chest computed tomography revealed a partial pericardial defect. Video-assisted thoracoscopic surgery was performed, and a small pericardial defect was confirmed at the level of the upper pulmonary hilum. We did not reconstruct the defect because of the improbability of cardiac herniation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Pneumopericardium combined with pneumothorax suggests the existence of a pericardial foramen. Partial pericardial defects could cause cardiac herniation or strangulation, and pneumothorax may worsen the protruding of the heart. Video-assisted thoracic surgery is an effective method to prevent the recurrence of pneumothorax and determine whether reconstruction of the defect is required.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Video-assisted thoracic surgery should be performed in the case of a pericardial defect combined with pneumothorax.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2020.09.085","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T02:48:02Z","timestamp":1600138082000},"page":"227-230","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Congenital partial pericardial defect confirmed based on spontaneous pneumothorax"],"prefix":"10.1097","volume":"75","author":[{"given":"Naoki","family":"Date","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teruya","family":"Komatsu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuji","family":"Fujinaga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"R1-53-20260114","doi-asserted-by":"crossref","first-page":"743","DOI":"10.1016\/S0025-6196(12)60630-2","article-title":"Congenital partial and complete absence of the pericardium","volume":"68","author":"Van Son","year":"1993","journal-title":"Mayo Clin.
