A keyword search was conducted to extract GICLs of the metacarpal bones out of MR reports in RA patients. There were nine GICLs extending from the subchondral bone region beyond the central diaphysis of the metacarpal bones on MR images in eight subjects with RA (seven females, one male). The age range was from 60 to 87 years with a median age of 65.5 years. The average disease duration was 13.1 years. As for the disease activity, one was low, six were moderate and one was high. None of the nine lesions were visible on radiography. The Steinbrocker stage distribution was as follows: I (n = 3), II (n = 2), and III (n = 3). Intraosseous cyst-like lesion of the metacarpal bones on MR images is a relatively rare manifestation in patients with long-standing RA. Although the lesion seems to be derived from subcortical bone break, it is not necessarily erosive in nature.<\/jats:p>","DOI":"10.3390\/jimaging7070113","type":"journal-article","created":{"date-parts":[[2021,7,12]],"date-time":"2021-07-12T01:41:07Z","timestamp":1626054067000},"page":"113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Giant Intraosseous Cyst-Like Lesions of the Metacarpal Bones in Rheumatoid Arthritis"],"prefix":"10.3390","volume":"7","author":[{"given":"Wanxuan","family":"Fang","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, North-12 West-5, Kita-ku, Sapporo 060-0812, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3433-5170","authenticated-orcid":false,"given":"Ikuma","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, Hokkaido Medical Center for Rheumatic Diseases, Kotoni 1-3, Nishi-ku, Sapporo 063-0811, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3494-5427","authenticated-orcid":false,"given":"Kenneth","family":"Sutherland","sequence":"additional","affiliation":[{"name":"Global Center for Biomedical Science and Engineering, Hokkaido University, North 15 West 7, Kita-ku, Sapporo 060-8638, Japan"}]},{"given":"Kazuhide","family":"Tanimura","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, Hokkaido Medical Center for Rheumatic Diseases, Kotoni 1-3, Nishi-ku, Sapporo 063-0811, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7293-7471","authenticated-orcid":false,"given":"Tamotsu","family":"Kamishima","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University, North-12 West-5, Kita-ku, Sapporo 060-0812, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1007\/s12016-016-8577-0","article-title":"Vitamin D Deficiency and Rheumatoid Arthritis","volume":"52","author":"Ishikawa","year":"2017","journal-title":"Clin.
