Overnight polysomnography revealed moderately severe obstructive sleep apnoea (OSA), which was managed successfully with oral appliance therapy with resolution of snoring and daytime fatigue. Structural abnormalities of the upper airways are known to cause OSA. Airway narrowing can result from bony structural abnormalities, nasopharyngeal growth, soft tissue redundancy, macroglossia, malignant and benign growth of the upper aero-digestive tract, and adenotonsilar enlargement. Clinicians should be encouraged to consider a diagnosis of OSA in patients with CLL when they present with symptoms of worsening fatigue.<\/jats:p>","DOI":"10.1136\/bcr-2018-228763","type":"journal-article","created":{"date-parts":[[2019,7,9]],"date-time":"2019-07-09T06:10:47Z","timestamp":1562652647000},"page":"e228763","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Obstructive sleep apnoea in a patient with chronic lymphocytic leukaemia"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8896-8945","authenticated-orcid":false,"given":"Gregory Paul","family":"Stimac","sequence":"first","affiliation":[{"name":"Medicine, Georgetown University School of Medicine, Washington, DC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asefa Jejaw","family":"Mekonnen","sequence":"additional","affiliation":[{"name":"Sleep Medicine, Rockville Internal Medicine Group, Rockville, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,7,8]]},"reference":[{"key":"2025082803515966000_12.7.e228763.1","doi-asserted-by":"crossref","first-page":"2203","DOI":"10.1007\/s00405-018-5071-8","article-title":"Day case adenotonsillectomy for paediatric obstructive sleep apnoea: a review of the evidence","volume":"275","author":"Wijayasingam","year":"2018","journal-title":"Eur Arch Otorhinolaryngol"},{"key":"2025082803515966000_12.7.e228763.2","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1111\/j.1440-1843.1996.tb00046.x","article-title":"Chronic lymphatic leukaemia presenting as severe obstructive sleep apnoea","volume":"1","author":"Nolan","year":"1996","journal-title":"Respirology"},{"key":"2025082803515966000_12.7.e228763.3","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdf277"},{"key":"2025082803515966000_12.7.e228763.4","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2007-06-093906"},{"key":"2025082803515966000_12.7.e228763.5","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2017-09-806398"},{"key":"2025082803515966000_12.7.e228763.6","doi-asserted-by":"crossref","first-page":"490","DOI":"10.2459\/JCM.0000000000000043","article-title":"Obstructive sleep apnoea\u2013hypopnoea and arrhythmias","volume":"18","author":"Vizzardi","year":"2017","journal-title":"J Cardiovasc Med"},{"key":"2025082803515966000_12.7.e228763.7","doi-asserted-by":"publisher","DOI":"10.1159\/000068423"},{"key":"2025082803515966000_12.7.e228763.8","first-page":"885","article-title":"Tonsillar lymphoma masquerading as obstructive sleep apnea - pediatric case report","volume":"57","author":"Toader","year":"2016","journal-title":"Rom J Morphol Embryol"},{"key":"2025082803515966000_12.7.e228763.9","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.50.5541"},{"key":"2025082803515966000_12.7.e228763.10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.77.5.689"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2018-228763","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:52:09Z","timestamp":1756378329000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2018-228763"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7]]},"references-count":10,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2019,7,8]]},"published-print":{"date-parts":[[2019,7]]}},"alternative-id":["10.1136\/bcr-2018-228763"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2018-228763","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,7]]}}}
