We present the case of a 57-year-old male with bone pain in the left hip joint that persisted for 2 years. CT and MRI images were performed and both were suggestive of ONFH. Unexpectedly, the histopathologic results of left proximal femur resection revealed the diagnosis of phosphaturic mesenchymal tumor (PMT), a rare mesenchymal tumor. His hip pain was obviously relieved after surgery, and the course of 1-year follow-up was uneventful.<\/jats:p>","DOI":"10.3390\/diagnostics13091632","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T04:55:50Z","timestamp":1683262550000},"page":"1632","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unexpected Phosphaturic Mesenchymal Tumor of the Femoral Head"],"prefix":"10.3390","volume":"13","author":[{"given":"Hui","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weijian","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenxin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6839-8527","authenticated-orcid":false,"given":"Ruiguo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Tianjin Medical University General Hospital, No. 154 Anshan Road, Heping District, Tianjin 300052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,5]]},"reference":[{"key":"ref_1","first-page":"100","article-title":"Guidelines for clinical diagnosis and treatment of osteonecrosis of the femoral head in adults (2019 version)","volume":"21","author":"Zhao","year":"2020","journal-title":"J.
