In this case, we present a 57-year-old patient diagnosed with anti-neutrophil cytoplasmic antibody (ANCA)-negative granulomatosis with polyangiitis (GPA) following a biopsy result of nasal granulomas, who was immediately started on immunosuppressive treatment. Years later, she developed progressive hypoacusis. Magnetic resonance imaging (MRI) revealed an extensive mass in the tympanic cavity extending to the mastoid. A biopsy of the mass was positive for Mycobacterium tuberculosis. Immunosuppressants were weaned and the patient was started on anti-tuberculous therapy with resolution of the complaints and findings. Tuberculous infections are difficult to diagnose and frequently mimic other illnesses, but in our case, we believe that an indolent tuberculous process was present from the beginning and evolved under immunosuppressive therapy.<\/jats:p>","DOI":"10.12890\/2020_001469","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T13:52:37Z","timestamp":1621950757000},"source":"Crossref","is-referenced-by-count":3,"title":["Not All ENT Granulomas Are Wegener\u2019s \u2013 Keep Tuberculosis in Mind"],"prefix":"10.12890","author":[{"family":"B\u00e1rbara Pedro","sequence":"first","affiliation":[{"name":"Clinical Immunology Unit, Hospital de Santo Ant\u00f3nio, Centro Hospitalar Universit\u00e1rio do Porto, Porto, Portugal; Department of Internal Medicine, Hospital Professor Doutor Fernando Fonseca, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Marta Meleiro","sequence":"additional","affiliation":[{"name":"Clinical Immunology Unit, Hospital de Santo Ant\u00f3nio, Centro Hospitalar Universit\u00e1rio do Porto, Porto, Portugal; Department of Internal Medicine, Unidade Hospitalar de Chaves, Centro Hospitalar de Tr\u00e1s-os-Montes e Alto Douro, Chaves, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Ant\u00f3nio Marinho","sequence":"additional","affiliation":[{"name":"Clinical Immunology Unit, Hospital de Santo Ant\u00f3nio, Centro Hospitalar Universit\u00e1rio do Porto, Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2020,2,19]]},"container-title":["European Journal of Case Reports in Internal Medicine"],"original-title":[],"deposited":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T13:56:19Z","timestamp":1621950979000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ejcrim.com\/index.php\/EJCRIM\/article\/view\/1469"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2,19]]},"references-count":0,"journal-issue":{"issue":"Vol 7 No 3","published-online":{"date-parts":[[2019]]}},"URL":"https:\/\/doi.org\/10.12890\/2020_001469","relation":{"has-manifestation":[{"id-type":"other","id":"1-56-1469-g1962","asserted-by":"subject"},{"id-type":"other","id":"1-56-1469-g1963","asserted-by":"subject"}],"is-part-of":[{"id-type":"other","id":"1-56","asserted-by":"subject"}]},"ISSN":["2284-2594"],"issn-type":[{"type":"electronic","value":"2284-2594"}],"subject":[],"published":{"date-parts":[[2020,2,19]]},"article-number":"14"}}
