A 65-year-old man presented to our emergency department with symptoms of sore throat and haemoptysis. He had no medical history. At arrival, O<jats:sub>2<\/jats:sub> saturation was 95% on 5 L\/min of oxygen with a mask. Results of a blood examination including a coagulation test were normal. Laryngoscopy showed enlargement of the left pharynx and a narrowed airway. Contrast-enhanced CT showed extravascular leakage of contrast medium inside the left pharyngeal haematoma. Fortunately, the haematoma did not lead to airway obstruction, and it decreased spontaneously. We finally diagnosed this case as spontaneous pharyngeal haematoma. When we examine a patient with a symptom of haemoptysis accompanied by sore throat, it is necessary to consider pharyngeal haematoma and to prepare emergency airway protection for acute upper airway obstruction.<\/jats:p>","DOI":"10.1136\/bcr-2021-242061","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T13:11:40Z","timestamp":1616418700000},"page":"e242061","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Unusual cause of acute upper airway obstruction: spontaneous pharyngeal haematoma"],"prefix":"10.1136","volume":"14","author":[{"given":"Kohei","family":"Okada","sequence":"first","affiliation":[{"name":"Internal Medicine, Akiota Hospital, Yamagata-gun, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Okazaki","sequence":"additional","affiliation":[{"name":"Internal Medicine, Akiota Hospital, Yamagata-gun, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihisa","family":"Ichiba","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Hiroshima Shiritsu Hiroshima Shimin Byoin, Hiroshima, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusuke","family":"Higashi","sequence":"additional","affiliation":[{"name":"Internal Medicine, Akiota Hospital, Yamagata-gun, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,22]]},"reference":[{"key":"2025082703431613000_14.3.e242061.1","doi-asserted-by":"crossref","DOI":"10.1177\/2058460117722813","article-title":"Non-Traumatic rupture of the superior thyroid artery with concomitant parathyroid adenoma and multinodular goiter","volume":"6","author":"Hanashiro","year":"2017","journal-title":"Acta Radiol Open"},{"key":"2025082703431613000_14.3.e242061.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0736-4679(03)00035-0"},{"key":"2025082703431613000_14.3.e242061.3","doi-asserted-by":"crossref","DOI":"10.1056\/NEJMicm1505596","article-title":"Spontaneous retropharyngeal hematoma","volume":"374","author":"Ditkofsky","year":"2016","journal-title":"N Engl J Med Overseas Ed"},{"key":"2025082703431613000_14.3.e242061.4","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1016\/j.ijoa.2018.05.003","article-title":"Spontaneous laryngeal haematoma leading to airway obstruction after vaginal delivery","volume":"36","author":"Eidesheim","year":"2018","journal-title":"Int J Obstet Anesth"},{"key":"2025082703431613000_14.3.e242061.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.bja.2017.10.021"},{"key":"2025082703431613000_14.3.e242061.6","doi-asserted-by":"publisher","DOI":"10.1183\/13993003.01813-2017"},{"key":"2025082703431613000_14.3.e242061.7","doi-asserted-by":"publisher","DOI":"10.4046\/trd.2012.73.2.107"},{"key":"2025082703431613000_14.3.e242061.8","first-page":"243","article-title":"Hemoptysis: evaluation and management","volume":"15","author":"Scott","year":"2015","journal-title":"Am Fam Physician"},{"key":"2025082703431613000_14.3.e242061.9","doi-asserted-by":"crossref","first-page":"1277","DOI":"10.1002\/hed.21213","article-title":"Cervical hemorrhage due to spontaneous rupture of the superior thyroid artery: case report and review of the literature","volume":"32","author":"Stenner","year":"2010","journal-title":"Head Neck"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2021-242061","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T10:43:21Z","timestamp":1756291401000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2021-242061"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3]]},"references-count":9,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,3,22]]},"published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1136\/bcr-2021-242061"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2021-242061","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2021,3]]}}}
