Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow\u2010up at 2 years demonstrated no recurrence or growth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear \u201cbilateral\u201d in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.21322","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T02:23:50Z","timestamp":1395714230000},"page":"603-606","source":"Crossref","is-referenced-by-count":11,"title":["Bilateral juvenile nasopharyngeal angiofibroma: Report of a case"],"prefix":"10.1002","volume":"4","author":[{"given":"Edward C.","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Head and Neck Surgery University of California, Los Angeles (UCLA) Medical Center  Los Angeles CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davin W.","family":"Chark","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of California, Irvine Medical Center  Orange CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naveen D.","family":"Bhandarkar","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery University of California, Irvine Medical Center  Orange CA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,3,24]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-6665(20)32905-4"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-199208000-00014"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0165-5876(80)90012-9"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016480310015948"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2011.05.020"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0194-59980300355-3"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2273.1986.tb01926.x"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1148\/126.3.703"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1148\/127.2.425"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198106000-00007"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.21337"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0165-5876(90)90083-4"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1159\/000224441"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200207000-00014"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00204142"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-197208000-00015"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1177\/019459987908700112"},{"key":"e_1_2_5_19_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199901000-00027"},{"key":"e_1_2_5_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0b013e3181897222"},{"key":"e_1_2_5_21_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100099722"},{"key":"e_1_2_5_22_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.moo.0000188859.91607.65"},{"key":"e_1_2_5_23_1","first-page":"668","volume-title":"Rhinology: Diseases of the Nose, Sinuses, and Skull Base","author":"Seiberling K","year":"2012"}],"container-title":["International Forum of Allergy &amp; Rhinology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Falr.21322","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/alr.21322","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T14:39:56Z","timestamp":1696603196000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/alr.21322"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,3,24]]},"references-count":22,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2014,7]]}},"alternative-id":["10.1002\/alr.21322"],"URL":"https:\/\/doi.org\/10.1002\/alr.21322","archive":["Portico"],"relation":{},"ISSN":["2042-6976","2042-6984"],"issn-type":[{"value":"2042-6976","type":"print"},{"value":"2042-6984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,3,24]]}}}
