Progression to a tension pneumothorax results in a medical emergency. Rare presentations with abdominal pain are possible and must be considered to expedite appropriate treatment of pneumothorax. Case Report: We report a case of a 21-year-old male with primary spontaneous pneumothorax who initially presented to the emergency department with right lower quadrant abdominal pain. History and physical exam were suggestive of acute appendicitis. A large right pneumothorax was incidentally found on computed tomography. Conclusion: This case highlights unusual presentations of pneumothorax. Emergency physicians should consider atypical presentations of chest pathology such as pneumothorax in patients presenting with symptoms consistent with an acute abdomen.<\/p>","DOI":"10.5811\/cpcem.53014","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T21:47:36Z","timestamp":1777499256000},"source":"Crossref","is-referenced-by-count":0,"title":["An Unusual Case of Spontaneous Pneumothorax Presenting as Right Lower Quadrant Pain: A Case Report"],"prefix":"10.5811","volume":"10","author":[{"given":"Timothy","family":"Crowe","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Cheatle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"29705","published-online":{"date-parts":[[2026,4,29]]},"container-title":["Clinical Practice and Cases in Emergency Medicine"],"original-title":[],"link":[{"URL":"https:\/\/escholarship.org\/content\/qt13x391fq\/qt13x391fq.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"}],"deposited":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T04:54:28Z","timestamp":1786596868000},"score":1,"resource":{"primary":{"URL":"https:\/\/escholarship.org\/uc\/item\/13x391fq"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,29]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,8,10]]}},"URL":"https:\/\/doi.org\/10.5811\/cpcem.53014","relation":{},"ISSN":["2474-252X"],"issn-type":[{"value":"2474-252X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,29]]}}}
