The cardinal presenting symptoms are unilateral nasal obstruction and recurrent, spontaneous epistaxis. Cases outside the adolescent male population are exceedingly rare and present a diagnostic challenge. We present the case of a man in his 30s referred to our tertiary skull base centre, presenting with left nasal obstruction. Examination showed left nasopharyngeal fullness without a discrete mass. Cross-sectional imaging detailed a 2.5\u00d72.1\u00d71.3 cm mass localised to his left sphenoid sinus with bony erosion. Due to the suspicion of malignancy, multidisciplinary consensus was to perform a diagnostic excisional biopsy and this revealed a JNA. He remains clinically well and asymptomatic following surgery. This case highlights the potential for subtle symptomatology in the presentation of these tumours and the challenge in diagnosing a JNA outside the adolescent male population.<\/jats:p>","DOI":"10.1136\/bcr-2022-254391","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T10:15:15Z","timestamp":1687169715000},"page":"e254391","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["\u2018Juvenile\u2019 nasal angiofibroma presenting in adulthood"],"prefix":"10.1136","volume":"16","author":[{"given":"Eoin F","family":"Cleere","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Beaumont Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"McLoughlin","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Beaumont Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter D","family":"Lacy","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Beaumont Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,6,19]]},"reference":[{"key":"2025082804003310000_16.6.e254391.1","doi-asserted-by":"crossref","unstructured":"Stubbs VC , Miller LE , Parasher AK , et al .
