These are very slow growing and are classified into low grade and high grade based on histological features. Surgical resection is the primary treatment with excellent outcomes, while chemotherapy or radiotherapy effectiveness is not known. Preoperative fluorine-18 fluorodeoxyglucose positron emission tomography\/CT (18F-FDG PET\/CT) is useful for predicting tumour grade and postsurgical prognosis.<\/jats:p>\n               <jats:p>A clinical case of a 31-year-old woman who presented with dyspnoea on exertion, cough and wheezing is reported. Imaging studies revealed a mass involving the left lower lobe bronchus and atelectasis. 18F-FDG PET\/CT showed uptake in the described mass with a maximum standardised uptake value of 9.7. Complete surgical resection was performed, and pathological examination revealed a high-grade mucoepidermoid carcinoma with tumour-free margins. Adjuvant chemotherapy was given and there is no evidence of tumour recurrence.<\/jats:p>","DOI":"10.1136\/bcr-2018-227969","type":"journal-article","created":{"date-parts":[[2019,2,1]],"date-time":"2019-02-01T05:36:49Z","timestamp":1548999409000},"page":"e227969","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Rare cause of lung atelectasis in a young woman"],"prefix":"10.1136","volume":"12","author":[{"given":"Paula In\u00eas","family":"Pedro","sequence":"first","affiliation":[{"name":"Pulmonology, Hospital Garcia de Orta EPE, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dolores","family":"Can\u00e1rio","sequence":"additional","affiliation":[{"name":"Pulmonology, Hospital Garcia de Orta EPE, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Lopes","sequence":"additional","affiliation":[{"name":"Pulmonology, Hospital Garcia de Orta EPE, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Despina","family":"Argyropoulou","sequence":"additional","affiliation":[{"name":"Pathology, Hospital Garcia de Orta EPE, Almada, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,1,31]]},"reference":[{"key":"2025082801062925000_12.1.e227969.1","first-page":"335","article-title":"Bronchogenic carcinoma; an analysis of 100 autopsy cases","volume":"111","author":"Smetana","year":"1952","journal-title":"Mil Surg"},{"key":"2025082801062925000_12.1.e227969.2","first-page":"1","article-title":"Mucoepidermoid carcinoma of the lung: a case report and literature review","volume":"2013","author":"Alsidawi","year":"2013","journal-title":"Case Rep Oncol Med"},{"key":"2025082801062925000_12.1.e227969.3","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.23048"},{"key":"2025082801062925000_12.1.e227969.4","doi-asserted-by":"crossref","first-page":"1400","DOI":"10.5858\/2007-131-1400-MCOTBA","article-title":"Mucoepidermoid carcinoma of the bronchus: a review","volume":"131","author":"Liu","year":"2007","journal-title":"Arch Pathol Lab Med"},{"key":"2025082801062925000_12.1.e227969.5","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/hyu016"},{"key":"2025082801062925000_12.1.e227969.6","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-10-232"},{"key":"2025082801062925000_12.1.e227969.7","doi-asserted-by":"publisher","DOI":"10.1177\/0218492316630494"},{"key":"2025082801062925000_12.1.e227969.8","unstructured":"Ishikawa Y , Alvarez Fernandez E , Aubry MC . et al Mucoepidermoid carcinoma.
