Magnetic resonance imaging demonstrated a well-circumscribed mass and isointensity compared to the skeletal muscle on T1-weighted imaging (T1WI) and low signal intensity mixed with high signal ranges on T2-weighted imaging. Dynamic gadolinium-enhanced fat-suppressed T1WI revealed mild and increased enhancement of the peripheral area in the early and delayed phases, respectively. On diffusion-weighted imaging (DWI), a heterogeneously high signal intensity corresponding to the peripheral enhanced area was observed, and the apparent diffusion coefficient values of the high-intensity areas on DWI were low. Malignancy could be suspected, so the mass was surgically removed. Pathological assessment revealed a fibrothecoma with minor sex cord elements. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; The tumor\u2019s preoperative diagnosis is difficult, although the possibility of this rare tumor from atypical findings on DWI and\/or dynamic contrast enhancement studies should be considered. <\/jats:p>","DOI":"10.1159\/000534798","type":"journal-article","created":{"date-parts":[[2024,1,17]],"date-time":"2024-01-17T22:00:33Z","timestamp":1705528833000},"page":"107-112","source":"Crossref","is-referenced-by-count":2,"title":["A Case Report: Ovarian Fibrothecoma with Minor Sex Cord Elements"],"prefix":"10.1159","volume":"17","author":[{"given":"Reina","family":"Miki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Kitajima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuo","family":"Maeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriyoshi","family":"Oki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2024,1,17]]},"container-title":["Case Reports in Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/cro\/article-pdf\/17\/1\/107\/4159192\/000534798.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/cro\/article-pdf\/17\/1\/107\/4159192\/000534798.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:50:43Z","timestamp":1745423443000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000534798"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1,17]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2024,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000534798","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.25001852","asserted-by":"subject"}]},"ISSN":["1662-6575"],"issn-type":[{"value":"1662-6575","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1,17]]}}}
