The splenic involvement in AAV is known to be rare, and that in MPA has not been reported to date. A 74-year-old woman was admitted owing to left arm numbness and weakness. The patient was diagnosed as MPA with vasculitic neuropathy. Her abdominal computed tomography (CT) revealed splenic infarction incidentally. The splenic infarction had been resolved at follow-up CT after treatment. If splenic involvement of MPA was not considered, treatment may have been delayed in order to differentiate other diseases. Herein, I report the first case of splenic involvement of MPA.<\/jats:p>","DOI":"10.3390\/medicina57020157","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T23:38:44Z","timestamp":1613173124000},"page":"157","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Microscopic Polyangiitis Presenting with Splenic Infarction: A Case Report"],"prefix":"10.3390","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3449-696X","authenticated-orcid":false,"given":"Sang Wan","family":"Chung","sequence":"first","affiliation":[{"name":"Division of Rheumatology, Department of Internal Medicine, School of Medicine, Kyung Hee University, 26 Kyungheedae-ro, Dongdaemun-gu, Seoul 02447, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,9]]},"reference":[{"key":"ref_1","first-page":"421","article-title":"Microscopic polyangiitis: Clinical and laboratory findings in eighty-five patients","volume":"43","author":"Cevallos","year":"1999","journal-title":"Arthritis Rheum."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1929","DOI":"10.1007\/s10067-020-04993-w","article-title":"Splenic infarction is not rare in granulomatosis with polyangiitis","volume":"39","author":"Gercik","year":"2020","journal-title":"Clin.
