We describe the case of a 38-year-old woman with relapsing GPA who presented with intracranial hypertension, followed by the appearance of cavitated lung nodules despite treatment with azathioprine. Clinical improvement and ANCA titre reduction were observed after rituximab treatment. We report a rare form of GPA relapse and highlight the challenge of following-up patients with GPA, in whom can be hard to distinguish relapse from the consequences of long-term immunosuppression.<\/jats:p>","DOI":"10.12890\/2021_002448","type":"journal-article","created":{"date-parts":[[2021,5,25]],"date-time":"2021-05-25T10:11:37Z","timestamp":1621937497000},"source":"Crossref","is-referenced-by-count":1,"title":["Granulomatosis with Polyangiitis: Recurrence or Treatment Consequences?"],"prefix":"10.12890","volume":"8","author":[{"given":"Andreia","family":"Diegues","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Unidade Local de Sa\u00fade do Nordeste, Portugal"}]},{"given":"Joana","family":"Tavares","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar Universit\u00e1rio do Porto, Portugal"}]},{"given":"Diogo","family":"S\u00e1","sequence":"additional","affiliation":[{"name":"athological Anatomy Department, Centro Hospitalar Universit\u00e1rio do Porto, Portugal"}]},{"given":"Jo\u00e3o","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar Universit\u00e1rio do Porto, Portugal"}]},{"given":"Diana","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Unidade Local de Sa\u00fade do Nordeste, Portugal"}]},{"given":"Josefina","family":"Santos","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar Universit\u00e1rio do Porto, Portugal"}]},{"given":"Guillerme","family":"Rocha","sequence":"additional","affiliation":[{"name":"Nephrology Department, Centro Hospitalar Universit\u00e1rio do Porto, Portugal"}]}],"member":"10397","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"10.12890\/2021_002448_ref1","doi-asserted-by":"crossref","unstructured":"<li>Yates M, Watts RA, Bajema IM, Cid MC, Crestani B, Hauser T, et al.
