Patient and methods: We report the case of a 25-year-old patient who was referred to us for an extension work-up for sinonasal chondrosarcoma confirmed by anatomopathological examination. Results: Facial magnetic resonance imaging (MRI) confirmed by a CT scan showed an osteolytic tumour process of the hard palate and walls of the left maxillary sinus that was locally advanced. Conclusion: The sinonasal location of a chondrosarcoma is rare. Characterized by cross-sectional imaging, confirmation was provided by histological assessment.<\/jats:p>","DOI":"10.12890\/2020_001933","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T09:52:37Z","timestamp":1621936357000},"source":"Crossref","is-referenced-by-count":3,"title":["Sinonasal Chondrosarcoma, an Unusual Location"],"prefix":"10.12890","volume":"7","author":[{"given":"Oumniya","family":"Abouhanine","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aicha","family":"Merzem","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vianney","family":"Ndayishimiye","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omar","family":"Amriss","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hasnaa","family":"Belgadir","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadia","family":"Moussali","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naima","family":"El Benna","sequence":"additional","affiliation":[{"name":"Department of Radiology, 20 August 1953 Hospital, University Hospital Center Ibn Rochd, Hassan II University, Casablanca, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2020,11,11]]},"reference":[{"key":"10.12890\/2020_001933_ref1","doi-asserted-by":"crossref","unstructured":"<li>Douis H, Saifuddin A.
