We report the case of a 59-year-old man who presented with pain and a swelling in the left cheek. Computed tomography (CT) demonstrated an expansile and radioluscent lesion in the left maxillary sinus. Incisional biopsy was performed, and the diagnosis was Brown tumor. Brown tumor must be considered in the differential diagnosis of expansile lesions of maxillary sinus.<\/jats:p>","DOI":"10.4103\/2156-7514.122325","type":"journal-article","created":{"date-parts":[[2013,11,28]],"date-time":"2013-11-28T09:06:36Z","timestamp":1385629596000},"page":"55","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Computed Tomography Findings of an Unusual Maxillary Sinus Mass: Brown Tumor Due to Tertiary Hyperparathyroidism"],"prefix":"10.25259","volume":"3","author":[{"given":"Canan","family":"Altay","sequence":"first","affiliation":[{"name":"Department of Radiology, Dokuz Eylul University, School of Medicine, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nezahat","family":"Erdo\u011fan","sequence":"additional","affiliation":[{"name":"Department of Radiology, Izmir Atat\u00fcrk Research and Training Hospital, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erdem","family":"Eren","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Izmir Atat\u00fcrk Research and Training Hospital, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sedat","family":"Altay","sequence":"additional","affiliation":[{"name":"Department of Radiology, Izmir Atat\u00fcrk Research and Training Hospital, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u015eebnem","family":"Karasu","sequence":"additional","affiliation":[{"name":"Department of Radiology, Izmir Atat\u00fcrk Research and Training Hospital, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Engin","family":"Ulu\u00e7","sequence":"additional","affiliation":[{"name":"Department of Radiology, Izmir Atat\u00fcrk Research and Training Hospital, Izmir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2013,11,28]]},"reference":[{"key":"10.4103\/2156-7514.122325\/ref-1","doi-asserted-by":"crossref","first-page":"7495","DOI":"10.4076\/1752-1947-3-7495","article-title":"Brown tumor of the maxillary sinus in a patient with hyperparathyroidism: A case report","volume":"3","author":"Proimos","year":"2009","journal-title":"J Med Case Rep"},{"key":"10.4103\/2156-7514.122325\/ref-2","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1016\/j.amjoto.2005.11.004","article-title":"Brown tumors of the jaws associated with primary or secondary hyperparathyroidism.
