Lung lesions are frequently reported as mass lesions or non-specific interstitial pneumonia, whereas organising pneumonia (OP) due to IgG4-RD is rare. Furthermore, limited information is currently available on hypertrophic pachymeningitis (HP). We herein report a case of IgG4-RD complicated with OP and HP. The diagnosis was confirmed based on the serum concentration of IgG4 and the results of salivary gland and transbronchial lung biopsies. HP did not respond to steroid monotherapy and was also resistant to rituximab and intravenous cyclophosphamide; however, the combination therapy of methotrexate and dexamethasone was effective.<\/jats:p>","DOI":"10.1093\/mrcr\/rxac025","type":"journal-article","created":{"date-parts":[[2022,3,31]],"date-time":"2022-03-31T07:32:55Z","timestamp":1648711975000},"page":"278-281","source":"Crossref","is-referenced-by-count":4,"title":["Refractory
